Hi some advice needed from you mum's out there. My little one just past 4 months has I believe gone into her 4 month sleep regression. I've read up on this and one of the main suggestions is getting baby to sleep on their own. My little one will not sleep if I just put her down. I leave her for ten minutes then she starts to cry. So here I am at 5am and she's wide awake and wants to play. Any tips on how I can encourage her to get herself back to sleep. Thanks.
