We got rid of swaddle at 9 weeks per pediatrician recco and there were a couple rough nights but now she’s sleeping better than ever, I think she likes having her hands free even if it sometimes still backfires with startle reflex
Omg my baby has been doing the exact same thing for the last couple of nights… the other night he stayed up until 3 am.. and then slept the entire day..
Mine did that around 9 weeks as well. I honestly think it was just a growth spurt. Give it some time. I know it’ll be rough for a few nights (possibly) but then she’ll go back to normal. My baby did.
I’d say stop swaddle and move to a weighted sleep sack! My son will be 3 months next week and we moved him into a sleep sack almost immediately (this is my 2nd). He has slept great ever since. We have Kyte Baby 1.0 Tog
When you say fussing is she actively crying? Some babies just fuss for a bit when they are in their bed/bassinet. My babies will fuss and squirm but they never cry out and eventually they will fall asleep by themselves. If she's breaking out of her swaddle it might be time to move her to a bigger size, we had to put our 2mo in a 3-6 because she kept busting out of her 0-3 one.
