Since your child is older a shorter body style might be good like the freehand since the child will have a bit more upper body freedom. Some of the taller carriers "may" make her feel more constrained and she may not like that if she's not used to it. Some of the makers will custom size for you too.
I fixed my other post to include the code to get the free shipping
There is also a sale for Patapum sale until Sunday, which is PATAPUM10, a 10% discount off the already reduced price of the Patapum in stock (normally $65, this makes it $49.50). This is the old style without the hood, to make way for the new style coming out in a few weeks.
Oh I forgot to say this is another sale thats going on at attachedtobaby.com too.
