never wake a sleeping child

parenting 101 right? except sometimes the mommy gene overrides all sanity and logic and one finds oneself waking the baby in an effort to confirm the baby is still breathing....I am curious clearly C is not a baby so when does this overwhelming an idiotic compulsion stop???? I just woke my almost 10 year old "baby" to make sure he was still breathing because he does not normally sleep until almost 8 on the weekends
