Idk if my little guy is just worn out from the last 2 days (2 month shots on Thursday and an eye doctor appointment yesterday) but he's been pretty sleepy today. I hope it's ok that he's sleeping this much. He will wake up, eat, then go back to sleep. He was only awake playing for about a half hour or so this morning. He also sounds congested but doesn't have a fever. Is it ok that he's sleeping so much??
