Baby won’t sleep help!

Z

My daughter is 3 1/2 months old. She just doesn’t sleep.

She has her own crib and cradle. She currently only sleeps in the cradle because she likes being rocked to sleep but we have to break her of that soon because she is getting too big for the cradle. She hasn’t rolled yet either so she still is swaddled at night with a sound machine.

We try to make her sleep at 8pm but it usually becomes a battle all the way until 1 Am when we give in and let her sleep with us.

We usually get up around 730 am and she MAYBE takes 2-3 hours worth of naps (spread out). She’d just rather be awake all day and night and usually isn’t even upset unless you try to get her to go to sleep.

Any advice?
