Last night my husband and I went to his parents house to hang out like usual. His step dad said something that just annoys me even hours later. He told me to feed my exclusively breastfed 2 month old son formula to keep him fuller through out the night so I can sleep more and so he can gain more weight. Now I have nothing against formula, but why start using formula if I produce enough breast milk for my son? He loves breast milk so much that he doesn't care whether it's from the breast or bottle, or even warm or cold. Why go out of my way to buy formula when my body produces all that he needs? Also, my son is 9 weeks old exactly and weighs about 10lbs 10oz. He's measuring 22.5 inches. He is a small baby and has been since birth at 7lbs 9oz and 20.5 inches. My son also sleeps from 9pm-2am and then wakes up every 2-3 hours after that. I get more sleep than I have been in awhile. I feel great from the sleep we get and I even have gone back to working 12 hour shifts. Lastly, he questioned how I know how much to feed my son. As if I haven't been doing it for weeks now and his weight and height have increased perfectly (Those are the doctors words). Why does he think he knows more than me when he hasn't taken care of a newborn in 20 years. I've done so much research and I know what my baby needs. I obviously feed him on demand. He gets 24-28 oz in a 24 hour period plus he gets the breast at night. Has anyone else's family members questioned the way they were taking care of their child?
