My 15 month old baby has been waking up between 4 and 4.30 everyday and will not go back to sleep. She's up for the day. And it's been like this for the last few weeks. Everyday and it's slowly killing me. She goes down in her cot between 7-7.30pm, her dad lies her down in her cot and she goes to sleep on her own but with him in the room. He sits next to her cot. She'll often wake up a few times before the early start to the day but she goes straight back to sleep once her dad goes back in and lies her back down. Each time she wakes up she stands and bounces in her cot. I swear to god if I hear the sound of that cot squeaking as she bounces in the middle of the night once more my head will just explode. I'm absolutely exhausted. She's an amazing baby and tbh she doesn't even seems that tired. But I am. Please give me your thoughts...
