Sleep advice

[user1465541658]

Hi my 18 month old DD goes to sleep perfectly fine has always slept through since early on. She was a early riser im talking anything from 4 to 5 and refused to go back to sleep for the good part of a year now however she wakes around 430 to 5:30 BUT after a cup of milk lies down and goes straight back to sleep till 6:30-7:00its extremely frustrating as she's never needed milk in the night before and not something at this age I want to carry on as we have to bring her downstairs or she wakes her brother and won't go back to sleep till she's had that milk so we sleep downstairs with her when she wakes for it.
How do we get her out of this habit any advice welcome but please note keeping her in her room with her brother for longer than 10 to 15 mins isn't a option as she wakes him

Maybe bring your son into your good for a weekend. Call it a sleepover 😂 then try laying your DD back down and leaving her to scream it out. Not everyone agrees with this approach but when our boy was 16
Months old he was waking 20+ times
A night and I was dead on my feet. So we pulled out daughters mattress in our room and let her have a sleepover for a week and now he sleeps 12 hours and goes down like a angel. Also if they aren’t in bunk beds, try putting a fan between their beds as it drowns out the sound if she is screaming! Xx

My DD had always been a good sleeper until about that age then got in to a habit of waking up. After trying all other alternatives we resorted to controlled crying. It took one bad night, two nights really and then she knew if she woke in the night she had to sleep. You could keep water in her room. Go in every few minutes and say quietly and calmly "we don't have any milk, have some water. Time to sleep now" and leave. Yes she'll cry. Just stay calm and keep returning every few minutes saying the same thing. After a few nights I'm sure it will solve the problem.
