Ok so yesterday my son had a bottle around 6:40pm he was awake for a short while then fell asleep. I was expecting for him to wake up around 9 or 10 for his last bottle of night but he never did. So at 12 I was getting ready to go to bed at thought well I'm going to change his diaper since it hadn't been changed since his bottle at 6:40 so I pick him up thinking he'll wake up if I change his diaper...but this kid slept through his whole diaper change!!!! So I brought him to bed since he wasn't waking up. I was thinking ok he's going to wake up in the middle of the night starving and want a bottle. But it's 9:26am and he's STILL asleep. I'm starting to get concerned with how long he's been sleeping......he's slept this late before but that's when he's gone to bed at like 11:30 or something. He's never slept THIS long before. Should I be worried?
