Carson is 5 weeks and 2 days old! He has still been relatively easy. He eats 5 oz every 3.5 hours. We switched him to Enfamil AR for a few days because of his acid reflux but didn't really see a positive change. He started getting constipated so we switched him back to regular Enfamil (which is much cheaper, by the way) and started him on Prevacid instead of Zantac. Hopefully, that will do the trick. We have realized that he is VERY gassy and we have to burp him after every ounce which makes bottle time a bit longer. He still only wakes up once a night. Last night he went down at 9:15 and didn't wake up to be fed until 3:30 am. He did, however, stay up until 5 am but then slept until 7 am. He weighed 11 lbs 2 oz at 5 weeks~BIG boy!! I thought he was going to be a quarterback but it looks like we may have a Linebacker!!!
