Well, I didn't sleep last night. Thea would not calm down. I finally almost got her there at like 8 this morning. So, hubby took her and him and a friend watched her while I slept. She fell asleep shortly after I did and when I woke up around 2, she was still asleep. Since she hadn't slept at all in such a long time and she had worn herself out from crying so much over the night, I let her be and I cleaned up. At 4 she was still asleep so I woke her up because she had only breastfed for a like 10 minutes and had about 2-3oz of formula before she fell asleep. She woke up breastfed some but she kept falling asleep so I gave her a bottle because she stays awake and finishes a bottle. She had 2oz and then afterwards she was happy so I put her in her swing and she fell asleep again.

Is she just, like, growing or catching up on sleep? And should I just let her be?
