We're in month 5! Lillie and Elliott are both doing well. At their 4 month check-up (they were actually in the middle of month 4 by the time we made it to the doctor) Elliott weighed 15 lbs 10 oz and Lillie weighed 14 lbs 7 oz. They are both in the 50-75 percentile for weight, they're doing great! Lillie seems to be going backwards in the sleeping through the night progress. She has started getting up two times during the night now instead of one. Elliott on the other hand gave me a present last night for his 5 month birthday... HE SLEPT ALL NIGHT LONG! From 8pm-7am. We were excited although it didn't mean a full nights sleep for me yet because of Lillie. So maybe she'll start making progress in the right direction soon. Elliott is smiling big and laughing some. Lillie is coming around. She's starting to smile a lot when she sees us. She can blow air out of her mouth and it makes a noise. We do it back to her and she does it back again. It's funny!
