DS had his 4 month check up, and though the doc said he'd doing great, I am worrying. He was 8 lbs. 4 oz at birth and dropped down to 7 lbs 11 oz in the hospital. He was 12 pounds 6 oz at 2 months. At his 4 month he was 13 pounds 14 oz. That's only a pound and half gain. At this rate he won't double his birth weight at 6 months. Aside from that, he's hit all his milestones, is alert, talkative and happy.
So, should I just relax and stop worrying or what?
