And you know what, for him, it works like a charm.
Call me a horrible mother, neglectful if you want, but he goes back to sleep. I honestly think that if you go right in when they wake they will expect it. So, I started letting him wait. If he was crying I went in after only a few minutes and try to calm him and then see if he falls back asleep. But most often he's happy so what's the shame in letting him lay there to see if he'll fall back asleep. In fact, today Gavin woke from his nap after only 1 1/2 hours. He usually sleeps minimum 2 1/2 but normally 3 so I knew it wasn't long enough. So, what did I do IGNORED HIM! He went back to sleep, but woke 30-40 minutes later. Again, I ignored him and mowed the lawn. He has now slept (off and on) for 3 hours and is still going strong. I'm sure I just jinxed myself and he will be up the second I post this.
So although my dearest boy can't walk, talk or chew gum (let alone all 3 at the same time) HE CAN SLEEP!! And for that I am grateful, especially since I've adopted this awful habit of staying up way too late. I still get to sleep 8 1/2 hours before he wakes me.
