One year old wetting the bed

[BLWC]

Our son is 1 year old (too young to be toilet trained) and every morning he wakes up wet through. I've tried using a few different types of nappies, pull-ups and lately I've even tried putting on 2 nappies at a time but it still doesn't hold all the wee in. He sleeps on his side so it always leaks out on the side and goes right through his pyjamas and grobag to the sheet. He has quite sensitive skin (regular nappies give him a rash) and until now I've always used eco, chlorine free nappies but have had to use huggies/pampers etc to try and stop the night wetting. I've also tried giving him less fluid at night but he gets thirsty then. I could set an alarm and sneak in and change him around 4am but wanted to see if anyone else had the same problem or suggestions?

Thanks!

I usually use a diaper that's one size up at night.

Have you tried inserting prefolds in the night time diaper so that it's more absorbing? I don't use cloth diapers, but that's what my friend did.
