DH gave Bubba 4oz of formula last night after I nursed him before bed. He was screaming and nothing would make him happy so that is what we did. He woke up at some point last night or this morning and nursed on both sides. So far this morning I have nursed him twice and he has been content Went to the doctor and he said to just supplement as needed but to keep breastfeeding. He was 18.5lbs today and 27 1/2" long. 2lbs and 2" gained since mid-September! He was off the charts at his last appointment and this one he is in the 85% percentile. He isn't as chunky looking as my oldest was at this age though but he is long.
