There's no single hardest stage, as different phases present unique challenges: the newborn phase (0-3 months) is brutally hard due to sleep deprivation and constant demands, while the toddler years (1-3 years) bring tantrums and communication struggles, and the early teen years (11-15) often involve intense social/emotional issues, mood swings, and boundary setting, with studies even suggesting pre-teens (11-12) bring peak parental stress. Ultimately, challenges shift from physical exhaustion in infancy to navigating complex emotions and independence in later childhood and adolescence.
1-3 Months
The first three months with your baby often seem the hardest. Sleep-deprived parents can feel overwhelmed, but that is normal and you will quickly learn how to read your baby's cues and personality.
The 7-7-7 rule of parenting generally refers to dedicating three daily 7-minute periods of focused, undistracted connection with your child (morning, after school, bedtime) to build strong bonds and make them feel seen and valued. A less common interpretation involves three developmental stages (0-7 years of play, 7-14 years of teaching, 14-21 years of advising), while another offers a stress-relief breathing technique (7-second inhale, hold, exhale).
A recent study suggests age 8 is the hardest to parent -- with 6 and 7 not far behind.
The "3-3-3 Rule" for kids is a simple mindfulness technique to manage anxiety by grounding them in the present moment: first, name three things they can see; next, identify three sounds they hear; and finally, move three different parts of their body. This engages their senses, shifts focus from worries, and helps them regain control when feeling overwhelmed, like during test anxiety or social situations.
The #1 worst habit for anxiety isn't singular, but avoidance (procrastination), poor sleep, and negative thought patterns (like catastrophizing) are top contenders, creating vicious cycles where anxiety fuels these behaviors, and the behaviors, in turn, worsen anxiety by preventing healthy coping and creating more stress. Other significant habits include excessive caffeine, poor diet, too much screen time, and social withdrawal, all disrupting the body's ability to manage stress effectively.
According to Dr. Deborah MacNamara, author of the best-selling book Rest, Play, Grow: Making Sense of Preschoolers (or anyone who acts like one), and the Director of Kid's Best Bet Counseling and Family Resource Centre: “Children can't be too attached, they can only be not deeply attached.
Early Childhood (0-4 Years) is the Most Physically Demanding
Parenting children ages 0-4 is intensely demanding, with round-the-clock caregiving—feeding, soothing, sleep deprivation, and constant supervision—leaving most parents chronically tired.
Parents age 40 and older actually show increased happiness with each child (up until 4 children which again is associated with decreased happiness). This difference in age occurs regardless of income, partnership status, health status, country, or what age you have children.
"70/30 parenting" refers to a child custody arrangement where one parent has the child for about 70% of the time (the primary parent) and the other parent has them for 30% (often weekends and some mid-week time), creating a stable "home base" while allowing the non-primary parent significant, meaningful involvement, but it also requires strong communication and coordination to manage schedules, school events, and disagreements effectively.
What Is a Good Mother?
Giving 20% of your attention will lead to 80% of quality time spent with your children. Your children crave your attention—not all of it; just 20%. Your attention is split into multiple areas: work, your marriage, your kids, your side hustle.
A 50/50 custody schedule can take different forms, such as alternating weeks, 2-2-3 or 2-3-2. Another option is a week-on/week-off schedule with a midweek overnight visit. Consider the child's age and schedule, proximity of the homes, and work schedules.
While it'll get easier with each passing day, you can expect caring for your newborn will be much easier by the time they're about 3 months old. As you're waiting with anticipation for when caring for your newborn gets easier, it's important to make sure you're taking good care of yourself.
The 2-hour rule for babies means they shouldn't stay in a car seat (or travel system seat) for more than two hours at a time, whether in or out of the car, because the semi-upright position can strain their developing spine and restrict their breathing, increasing the risk of low oxygen levels, especially for newborns and preemies. For long journeys, parents should take breaks every two hours to take the baby out, allow them to lie flat for a while, stretch, and feed, ensuring they get proper head/neck support and circulation.
Physical Signs:
The American Sociological Association recently conducted a study on this very topic and found that parents are more likely to be depressed than their childfree counterparts. In fact, people without kids were happier than any other group, including empty nesters.
The period from 0 to 5 years of age is often referred to as the "Golden Period" of child development. During this crucial phase, a child's brain grows rapidly—even reaching 90% of its adult size.
Here's what they found: People are happiest when they live with 4 to 5 people. The relationship between household size and happiness forms an “inverted U-shape.” That means happiness rises as the household grows, peaks at 4 or 5 people, and then drops again in very small or very large households.
Most mothers are exhausted and annoyed at motherhood because their children may cry and whine a lot, not listen, and do dangerous things that they're not aware are anxiety provoking for parents. Motherhood is hard and it's true that many moms hate being a mother. It's ok, you're not alone.
The "9-minute rule" in parenting, or the 9-Minute Theory, suggests that focusing on three specific 3-minute windows each day creates significant connection and security for children: the first three minutes after they wake up, the three minutes after they return from school/daycare, and the last three minutes before sleep, emphasizing distraction-free, quality time to boost well-being and reduce parental guilt.
The "42% rule" for burnout suggests dedicating roughly 42% of your day (about 10 hours) to rest and recovery activities like sleep, hobbies, exercise, and socializing to prevent mental and physical exhaustion, countering the "always on" culture that leads to burnout. It's a science-backed guideline emphasizing that sustainable success requires balancing intense work with sufficient downtime for your brain and body to recharge, not just a quick nap.
The "3-3-3 Rule" for toddlers is a simple mindfulness and grounding technique to calm anxiety by engaging their senses: name 3 things they can see, identify 3 sounds they can hear, and move 3 different parts of their body (like hands, feet, head). This helps shift focus from overwhelming thoughts to the present moment, acting as a "brain reset" for emotional regulation during meltdowns or stress, making it a useful tool for building emotional intelligence and control.
It is more common for boys to become overly-attached to their mothers. An over-attachment is unhealthy because both parent and child become too inter-dependent on each other. In worst case scenarios a Symbiotic Relationship develops in which neither child nor parent can function without the other.
Red flags in 3-year-old behavior include extreme aggression (hitting, biting), persistent defiance, severe separation anxiety, lack of interest in peers, regression in skills, inability to self-soothe, unusual fears, and significant delays in language or motor skills, suggesting potential issues beyond typical toddler development, like sensory processing problems or ADHD, warranting professional guidance.
