You can get some that are up to 4 years, think it’s the grobag brand. I’ve found them all on vinted.
I just up the size x
My LG is quite long and we’re using 18-36 months and she’s still got space x
@Bex thank you. What brand please? I find that some are quite a bit shorter than others.
We’re using superlove merino ones, the ones with feet for us. The length is adjustable. They’re expensive, but we kept an eye out on vinted and got a couple. They’re lovely.
Ones with legs in from Amazon - in a size she is in for clothes
My LO is quiet tall and we use LWC bags (18-36 months) they have plenty of room
