My 4 month old lo is sometimes (50%) of the time able to go through his 45 min. mark at the first am nap (9 am). For the next nap he is not able to, so I've started wake to sleep, or going in at the 35 min mark to help him back to sleep- sometimes successful. He's on a 4 hour EASY.... my question is, do I go in in the morning anyway? When do I step back and let him do it? I'm afraid that my presence sometimes disturbs him. I don't really know when he is going to be able to do it on his own... Any advice/ideas? :?
