Hi Jane, I have a 3month old who is currently 13 lbs. I have been wearing him in a homemade mei tai, "froggy style". He is starting to fuss every time I put him in and I think it is because he is getting to big for his legs to be tucked up. The mei tai that I have is not conducive to front wearing with his legs out as it is very wide. I am not comfortable using a back carry with him at his age. I also have older children whom I would like to be able to wear on occasion. I love the mei tai for its ease of use. I would like one carrier to be all things!! I have tried pouch slings and the Moby wrap, pouch slings are okay, and I really do not like the Moby wrap. I am looking at purchasing either an Ergo or a Pikkolo. I have never tried either one and there is not a store near me that carries them so I would have to order one online without trying it on. Is there a recommendation that you could make?
