Hi girls,
I don't have any advice either I'm afraid but my 6 month LO is doing the same! Waking anytime from 4 and just chatting, raspberries etc, occassionally moaning but not much. Mostly goes back to sleep, sometimes doesn't (yawn!) We haven't dropped the catnap yet as his naps aren't long enough to get us past 3pm so can't make BT.
If it's a habitual waking at 4 maybe wake2sleep would work?
