I breastfed two of my boys.....(two older boys not biologically mine....but they are mine) So with Devan (noncf) 4 mos....and supplemented....he was starvin' all the time and I couldn't keep up the supply. With Wade (cf) I fed him 7 mos. Supplemented after 4 mos. I truly believe it helped with sinus/ear issues.....Wade is pancreatic sufficient....but VERY GASSY....I think breastfeeding him did help with that too....not alot but I would be afraid to think how worse it would've been with formula only.
I'm all for breastfeeding......I think there are numerous health benefits, and definitely bonding benefits. Not to mention its FREE....but very time consuming, and very exhausting.
