My DS is 11 weeks old, he's always been a very vocal baby - shouting and squeeling and cooing to himself constantly, especially in the morning when he wakes up. He's also very smiley and very happy to interact with people and look at their faces. Last week he started laughing too.
This week he seems withdrawn, he isn't making much eye contact with me and smiles are like getting blood from a stone. He's also seemed really sleepy - sleeping away a lot of the day. At night he keeps waking himself up crying out but when I check on him he's gone back to sleep. He's also REALLY wriggly in his cot when he's semi asleep.
Do you think he's just working on other milestones right now, or should I be worried? he hasn't got a temp or anything like that.
