My dd is 4 months old today.

She generally doesn't settle on her own and also doesn't like to sleep on her own either.
She is rocked or held to sleep sometimes in our swing. During the day she doesn't feed to sleep but at night because we co sleep its a boob in the mouth in bed and once done she is straight back to sleep. I don't change her at night unless she has pooped.

I can prob count on one hand the amount of times she has self settled as such.

My SILs baby on the other hand from day one would just fall asleep on her own no worries so all babies are completely different.

Once bubs is over 6 months we might begin the no cry solution and see how that goes because I would like to be able to put her down during the day
