18 weeks! Gia had her 4 month appointment yesterday. It went ok, but she lost 1/2 an ounce. She's been sleeping 12 or 13 hours at night, so I think that is why she lost weight. We are going to start feeding her again after she's gone to bed, and waking up one time in the early morning to feed her again. Hopefully that will help her get back on the weight gain track. Since she's been sleeping so much at night, though, she is hardly sleeping at all during the day. Like, less than two hours collectively between her morning and afternoon nap. Not good. So, we're still working on all this. Sheesh, its not easy! Gia's been a bit less talkative this week, but she has been laughing a lot! its so cute! I love her giggles!
