We have a new baby, 5 days old today.
My first one was not a great sleeper and hardly napped during the day, but we are now finding out that he was a fab sleeper, actually sleeping 2-3 hours in a row, giving us time to sleep a bit between feeds.
Newborn won't settle at all. Unless on my or partner's chest. The moment we take him off and put down, he wakes instantly, does not matter if we let him sleep 5 or 30 minutes, he waskes up wailing and does not stop and escalates into a super loud cry, we tried to give him time to settle (I know at 4 days old he will not be able to do that yet though), pat him gently, warm his matress, play white noise.
We tried the crib, we tried cosleeping. In the first 5 days we have already fallen asleep with him on our chests instead, and we are freaking out as it's dangerous, but partner and me are totally knackered and it just happens. We have a hyperactive toddler, so can't catch up on sleep during the day either. Baby is very restless and super light sleeper during the day too and sleeps well in his bouncer or sling, but not in the cot.
I tried swaddling (my firstborn hated it) which worked for 2 wonderful hours before it stopped working and went back to normal.
I know it's early days, but I judt dont know what else to try.
