My 13 month old son is currently waking up every single morning crying hysterically. He sleeps in his cot from around 7.45pm until 4.30am (sometimes we have more night wakings). I normally then bring him in to bed with me, where he drops back off (usually) until he's ready to wake up (between 6-6.30).
When he does wake up for the day, he is immediately really upset, despite me being right there with him. He doesn't want cuddles and pushes me away and throws himself backwards. He doesn't want water/milk. He only stops crying once I turn the light on and start our day.
Do you think he's essentially just having a tantrum because he wants to get up? He does it in the early hours sometimes too and I just have to sit and wait until he calms down and goes back to sleep - sometimes taking an hour. It's an awful way to start the day and I wish I knew how to help him wake up happier!
