How?

is my newborn son (well 4weeks) into medium nappies already

Yikes! My 22month old still fits some mediums!!!

its all those mars bars he's been sneaking in the night lol!

He does A LOT but he has a tongue tie and lip tie so figured he was just making up for that! little chunk and he is really long too

Evie was the same, xs oww lasted about 3 weeks glad I only had a few and they were preloved. I found the rise was too short on most things and that in mediums leg gape was our enemy.

He still fits his smalls but mediums are a nicer fit round the waist thing is he has a teeny bum XS fit him for about 2 weeks

So odd aren't they, we couldn't get a large on Evie shed be swamped but have found m/l green panda fit nicely and itti mediums fit nice too if a little short on the rise. She's so long and skinny that larges fall down and have huge leg gape.
Have you tried a mama knows yet? They are fab, squishy and onesize so should last a while. She's on fb so maybe see there and at £7 a pop can't go wrong

I *think * they are same pattern as the one size i made and so far that has been one of my fave nappies so i might just make some more.

i must have a tiddler as my 3month old is still on the second tightes on all of his smalls.
