3 year old sleep help!!

[Luna20]

My LO is a month shy of turning 3. In the last week he's started waking up at around 1am and is awake for exactly 3 hours and will then go back to sleep. No matter what we do, it's the same every single night. Whether we get up with him, keep him in bed, bring him in to our bed, get him a drink or food or not etc etc. He still naps for about an hour a day and if he doesn't he gets extremely over tired and feral. But we have tried no nap days to see if this helps with his night sleep but it hasn't made a blind bit of difference. Either way, nap or no nap, he will wake up for 3 hours in the night. My friend suggested magnesium on his feet so I might try that but I'm thinking it's developmental/some sort of leap and beyond our control and wonder if anyone experienced the same? And if you did.. how long did it last? 😩🤞🏻

Also wanted to add, his eating has gone completely out the window too. He's never been a huge eater, not picky, just never ate loads. But this past week or so he has been refusing all meals. He will have a few bites of something and be done. Won't even consider breakfast or lunch. He will sometimes nibble on carrot sticks, a banana etc but mostly it's a few bites and won't look at it again. I don't know how he's got the energy he has!! Some one please tell me this is some kind of leap and he's going to go back to some sort of semblance of normal soon 😅😩

You need to see the GP. The poor eating is concerning if it’s really just nibbles on banana and carrot all day. Also, it could be linked either like he’s waking from hunger or for example enlarged tonsils can cause swallowing issue and therefore poor eating, and also sleep apnea can lead to night wakings. You definitely need a medical opinion.

Is he really only nibbling a bit of a banana and carrot all day? I think parents can sometimes over exaggerate how little their children are eating but when you actually look at what they eat over the course of a week they're taking in what they need to.

You've not said what time he goes to bed. I would drop the nap and put him to bed earlier. He might need his dinner at 4 and to be in bed no later than 6pm. So pyjamas, brush teeth, and bedtime stories at half 5. Soft lamp in his room, everything calm and quiet and into bed at 6. My son is the same age and goes to bed at 6 on the dot and I know other children his age who go to bed at half 5. All sleep through until 6 or 7am.
