11 week old only having 30 minute naps and is crying most of the day with pure overtiredness. She gets herself to sleep in the Moses basket and I give her time to settle back when she wakes but she can't do it and gets so upset. I try and resettle but that also doesn't work. The same happens in the sling or pram. If she sleeps on us in the dark sometimes we get her back with rocking when she wakes. This isn't sustainable as I have an almost two year old as well. She has white noise and black out. We have tried going in just before the End of the sleep cycle but it doesn't work. Any tips? I wouldn't mind if she was content but she is crying most of the day. She is awake max 90 mins between sleeps.
