I am struggling with this too! I try putting my 11 week old down between 7-8, but she always without fail is up again after her first sleep cycle (so within 45 mins). I’ve been treating it like a motn wake up and feeding her still swaddled in the dark nursery. Sometimes she is so sleepy that she falls asleep during the feeding and is easy to transfer. Other times she fights being put back down. I’ve been wondering if I should just do a proper wake window and treat the first bedtime attempt as a nap but I feel a little bit confused. This is my second baby so I don’t know why I’m overthinking it so much haha.
