Hi everyone! DS (just over 4 months) is a pretty good sleeper. He puts himself to sleep in his crib usually between 7:15-7:45 pm. Sometimes will stir around 11-12 but usually just needs a quick side rub (he's a side sleeper) and doesn't fully wake (we don't DF). Then lately he wakes once around 3-4am. This morning it was 3:50. Rubbing his back, etc won't calm him down so I usually give him a diluted bottle at this time, change him and put him back in crib. BUT if he's already slept 8 hours or more, I can't get him back to sleep. He'll try for a while, grunting, moaning, talking, fussing and I try a few times to settle him. But he gets more upset. As I don't want him to wake DD (he sleeps in a loft area for now right outside her room), I often then get him and put him in the swing downstairs (still dark) where he will still take a bit but eventually fall asleep (at which point I turn swing off if I remember) until up for day.
Couple questions:
1. Is the swing a bad habit to get into early morning like this? If so, what else should I do?
2. Instead of feeding him at that 3-4 am time should I just try transferring him to the swing first? Maybe he will wake up less that way and maybe the swing is less of a hard prop to break than a middle of night feeding?
He doesn't suck his thumb or pacifier and he does have a muslin and a small teddy he sleeps with...
TIA!
