my 11 month old has started waking at 5am, he used to sleep 7 till 7 a few weeks ago. it started with him reducing his 2 hour and half naps to 2 half hour naps and i spoke to heath visitor about this and she said he maybe doesn't need naps anyone but that's clearly rubbish as he's now waking at 5!
iv tried everything like nappy change medicine more blankets a cuddle ignoring water checking at intervals. he isn't on the move at all only rolling which is sometimes a problem. iv even sat and held his hand and sshh him.
I'm desperate as I'm exhausted as a student on only 5 to 6 hours sleep and he's a miserable baby particularly in afternoon. i know this isn't enough sleep total of about 11 and half to 12 hours sleep a day for him like 2 hours too little!
11/12 months to 19 months were "disturbed sleep" in this household: DS had slept through since 12 weeks old, but teething was hell (although his day time naps remained good).
DS used to consistently nap 45 minutes in the morning and 1hr 15 or so each afternoon. I brought his naps together into one 2 to 3 hour nap (from about 12.30pm) each day a 14 months. He still has one 1.5 to 3 hour nap each afternoon at 2yr 8 months.
We just rode through it. My stance has always been "no getting up before 6.30/7am" (never wanted to get into bad habits). Generally he only wanted reassurance. We put a spare mattress, duvet and pillow on the floor right next to his cot and took it in turns to go and sleep nex to him (often holding his hand). That way we could either drift back to sleep, in and out of sleep or at least be warm and comfortable...
They are all different and so are we as parents - it is finding a way to cope with it that suits both them and us.
This may sound daft, but he may need more sleep in the day. My ds started cutting down his day naps, then would get overtired at bed time, therefore going into a deep sleep, then waking early. So he had 15-20 mins one nap in the morning to get over his early waking but meant he was sleepy at lunch so he had 2 hours at lunch. This then revived him for the afternoon, ready at 7 tired, but not knackered. 2 days later he was back to normal. Worth a try
