Ds is a small 5 month old and until recently he always enjoyed sleeping in the carry cot, but if he is in there too long he starts screaming. I'm not sure whether he wants to sit up or whether he is too hot (due to current warm weather) I tried him in the pushchair but the harness is as big as him and comes right up to his chin. Just wondering at what age you moved your dc from the carry cot to the pushchair seat and at what age you used the reclined seat position.
