Boba carier/frog-leg positioning help please!

[Dozeyland]

DD is 4months next weds, weighs approx 14lb 9... but her legs don't sit right in my carrier. it says for babies at 5months onwards or 15lb...
she is a long baby, good amount of chub on her but she doesnt seem to be able to do frog-legs!?

Advice please!

What do you mean by frog legs? Tucked underneath her? Or hanging out of the carrier?

If you're talking about legs out, then is the base of the carrier a bit wide for her at the moment? The fabric needs to go from the back of one knee to the other, which should put her naturally into a 'froggy' position with her legs splayed and her bum slightly lower or level with her knees.

If it's too wide, she won't be able to bend one or both of her knees and might end up wonky.

I hope that helps. It's a bit hard to understand what you mean by "doesnt seem to be able to do frog-legs" without actually seeing her in the carrier.
