My boy is 2 years old and quite small and skinny for his age, he usually wears 2T for pants and 18m shirts so I took the size 0 as recommended.

The first night was okay however the second time he had it on the problems started. The pul was wet in the morning so his pyjama was damp, it wasn't really leaking but the absorbency wasn't enough. I tried adding a booster but it was then way too tight too put on my boy. Very hard to put on and off and no space for boosters. I'm quite disappointed, maybe if I had ordered a size up it would be fine but I'm not convinced. I'm gutted I spent so much for it.

Also all the bulk is at the back of diaper so not ideal for a boy I find since there is only a skinny part in front.

Too big ordered size 2 despite guidance suggesting size 3 but still too big although size 1 would probably be too small. They also feel and look too big and bulky. Insert seems too long to fit cover and ends up gathering inside so little boy doesn't really like the feel of them. Wanted to try and get little boy out of nappies at night and thought these would help but still very nappy like rather than pant like so he feels they for baby. Also have had some leaking normal wears size 7 nappy pants with no leaks but he was a bit damp with these only worn a handful of times as he refuses to wear them. Waste of money for me I am afraid.

Our daughter who is 6 is struggling to stop wetting the bed at night. Disposables were becoming uncomfortable for her and we were sad that we were still adding to landfill.
We decided to try these out and they are just brilliant. She is dry all night and they wash and dry very easily.
Our daughter is tall and wears size 7-8 clothes so we originally tried the size 4 but it was too big around her legs. We exchanged very easily for size 3 and these fit perfectly.
An excellent washable option for bigger kids.
