My 11 week old just screams lately. I don’t think it’s because his stomach hurts, because when it does, he pulls his knees up, etc. he isn’t hungry, and I’m holding him. So, is it normal for his age to fight sleep? Like I feel like he is screaming because he is tired. Because nothing I do can make him stop. But he always falls asleep after his crying fits...other than that, he hardly ever cries. Just wondering if fighting sleep and screaming like that is common for his age?
