Can't sleep won't sleep

[bigbadwritersblock]

12 week old DD can't nap at all during the day -ages beside herself with over tiredness and its affecting everything - DS (4) can't eat as ages always crying

We have tried rocking her shhing her pram - only thing that works is a moving car and I can't drive a 4 yr old all the time.

Any advice greatly recd

She is breast milk fed by bottle

White noise? soothing music? I've heard great things about hair dryer noise?

Is it possible that your 4yr old might be keeping baby awake? I'm pretty sure my 3 month old is awake most of the day when my 2 year old is at home as she is quite noisy!

She just won't sleep unless its in something moving - pram, my arms or car -has to be moving x 4 yr old doesn't get a chance to wake her up as she just won't drop off

Have tried white noise and will give it another go thanks
