Do you let your little one ( still in a crib) play in the morning before you go in to get them ? If ds wakes up happy I let him hang out in there for a few minutes so I can snooze off an on. He likes to blow raspberries , squeal and giggle and as long as he's happy I don't see the harm in self entertainment for 10 minutes or so !
When my youngest was still in a crib he wouldn't make a peep when he woke up. He'd play in his crib for a while and then when he was ready to get out he'd call for me (loud "yelling" and then "mamaaaa" when he could talk). I never saw anything wrong with letting himself for a little while. Even now he's four and he gets up before me and plays for a while before coming get me (whether I'm still asleep or just doing things downstairs).
With my older two, as soon as they were up, the whole house was awakened. Amazing how very different each child is.
