Feeding: You can enhance your breast milk by pumping and increasing your fluid intake. If you want to give the formula, similac is a good option, sometimes the children don't like the taste, try it first thing in the morn, when the baby is really hungry.

Be patient: It take some time for babies to adjust to a new feeds. If you don't have enough milk, you might also need to relax and have enough sleep and liquid in your diet. And just be a little bit patient. Sim 20 cal advanced is a good formula to supplement with. Be sure that any formula you supplement your child feeds there is a supplemental iron in it.
