You know it might be time to change your baby's formula if they have persistent symptoms like diarrhea, extreme fussiness, excessive gas, vomiting, rashes, bloody stools, or poor weight gain, indicating intolerance or allergy; however, always consult your pediatrician before switching, as they can help identify the issue and recommend a suitable hypoallergenic, sensitive, or specialty formula, ensuring a gradual transition to avoid further upset.
When to switch baby formulas
What are the Signs of Formula Intolerance?
Yes, it's perfectly fine to switch formulas. More or less, they're all pretty much the same anyway. The only thing that really varies is the flavour, which your little one may or may not like.
It usually can take around 2 weeks for baby to fully adjust. I switched from Enfamil to similac and used what google suggested when switching formula which was mixing half and half and gradually going from one to the other.
Abrupt changes can sometimes upset your baby's delicate digestive system. To help your little one transition and adjust to a different texture or taste, a slower phased approach can help them get used to it. You can start this by swapping one feed a day of your current formula, to your new one.

Soy-based infant formulas (plant protein but often soy protein isolate) Specialty formulas (in some regions, hydrolyzed rice formulas exist; availability varies)
Holding your baby is best. The way your baby sits in an infant seat can make spitting up more likely. Don't jiggle, bounce, or actively play with your baby right after feedings. Make sure the hole in the nipple is the right size and/or flow for your baby.
The "5-5-5 Rule" for milk refers to guidelines for safely storing expressed breast milk: 5 hours at room temperature, 5 days in the refrigerator, and 5 months in the freezer (though CDC suggests up to 12 months). It's a helpful memory tool for new mothers, but there's also a separate "5-5-5 rule" for postpartum recovery, recommending 5 days in bed, 5 days on the bed, and 5 days around the bed for rest after childbirth, say this article from Franciscan Health and another from The Bump.
It's safe to mix and match infant formulas if you are following standard mixing instructions. Really. Although spitting up or gassiness is usually not due to the protein in formula (cow's milk versus soy versus hypoallergenic), sometimes changing formula helps new babies and their parents who worry.

Why Does SIDS Peak at 2-4 Months? The widely accepted explanation for the SIDS peak has to do with the timeline of brain development. “Up to 4 months old, the part of the brain that controls breathing and wakefulness is under a lot of development,” Juliet explains.
Hold your baby until they're in a deeper sleep. Babies start in 'active sleep' (with faster, uneven breathing) and move into a deeper sleep after about 20 minutes. That's a good time to transfer them into their sleeping place. Many babies don't like being put down into a cot.
The hardest week with a newborn is often considered the first six weeks, especially weeks 2-3, due to extreme sleep deprivation, constant feeding demands, learning baby's cues, postpartum recovery, and a peak in inconsolable crying (the "witching hour"), making parents feel overwhelmed as they adjust to a new, exhausting routine. While the first week is tough, the challenges often intensify as the baby becomes more alert but still fussy, with major developmental hurdles like cluster feeding and increased fussiness peaking around 6-8 weeks.
