Why can't my baby fall asleep by herself?

[Mamabear04]

Is it normal for a 12 week old to not fall asleep by themselves? My DD hasn't been able to fall asleep by herself unless being rocked or bounced on an exercise ball or being walked in the pram. Will this ever change and if so when?

@Harrysmummy246 she used to sleep in the sling but has cried every time I try to put her in it the past few weeks. I long for the day she likes it again so I can get stuff done around the house while she naps!

So nice to see replies that state it's normal and not many mentioning sleep training. That culture is very unrealistic and makes normal biological infant sleep appear abnormal and puts unnecessary pressure on parents.

OP, certainly don't listen to the obsessed culture society seems to have about independent babies... Self settling can't be forced, it's something we develop on our own. There's nothing wrong with you or your baby
