Ask your baby's pediatrician if his weight is good and if it's correct for his height. It's all about proportion here, not just the pounds.
Give the right amount of formula for your baby's weight.
Hold pacifier use to a bare minimum -- like when it's 2 a.m. and you're ready to scream. Other than that, it's not a good thing. Just ask a speech pathologist -- too much pacifier use can interfere with making sounds and forming words. Keep that cork out of their mouths
Wait until your baby is at least 4 months before considering introducing solids. Wait until he's 5 or even 6 months if you can. Babies have a lifetime of eating ahead, and it will be worth the wait.
Learn to recognize when your baby has had enough, and then honor that. It's the beginning of great communication.
