Is it okay for me to give my newborn breast milk and formula?

Yes. Many physician organizations have endorsed the idea that exclusive breastfeeding is the best for baby and mom for the first year after birth. But, it is more than ok to supplement with formula when you chose to. While we encourage breastfeeding, one should never feel bad or guilty for supplementing or switching to formula feedings.
Yes. Breast milk is the gold standard of infant nutrition and it is our responsibility as physicians to both promote and support healthy breastfeeding. There are many times, however, where it is not only okay to use formula, but preferred. Talk to your pediatrician if you have concerns about how your infant is feeding.

Depends. Your child is not going to be allergic to the human based proteins in your milk, but could be sensitive to partial proteins from your diet.

Yes. Your baby may be sensitive to what is in your diet. Cow's milk intolerance is not uncommon, for example.

My newborn has not pooped since I switch to breast milk what should I do?

Probably OK. Breast milk is better digested than formula. At 3-4 wks of age breast fed babies may have a decrease in frequency of poops to every few days. Switching between breast and bottle can contribute to variation in frequency and character of poop. If your baby is eating well, belly is soft, and s/he is not fussy/irritable/crying more than usual it's probably fine. If you are worried, see your doctor.
Wait. Breastfed infants often skip several days between bowel movements. As long as they are well hydrated, feeding well, and not otherwise ill appearing, then simply wait. If the stool is soft when it comes, then your baby might develop a new stool pattern of every few days. Constipation in infants is defined by consistency of stool, not frequency. It should be soft.
