My daughter will cry at night even when feeding and I just cuddle and shush, she's restless and like she is fighting it. My eldest was the same, but the 2 in-between would just lay down close eyes and sleep lol. I think it just depends on the baby! X
In the day it's walks out in the pram or a car walk. Won't settle in the cot (but need him to self learn). At night he self settles but we spent some time encouraging/ practicing this as it was the only way to get through the 4 month sleep regression. I've dropped the contact naps as he wouldn't settle anymore and we had so many overtiredness dramas. I'm a bit nervous teaching him to self settle for day naps as he's impossible to calm down but I know eventually I need to do it, especially approaching 6 months x
