My DS2 is 6 months about 20lbs. I have been wearing him in a boba stretchy wrap but it is starting to get uncomfortable and DS wants to be able to look about. I'm thinking about trying high back carry. I have a boba 3g as well but I think it is too big still it really hurt my back to carry him. I used it no problem with DS1 when he was a toddler. I'm thinking a mei tai or woven - but a woven scares me. I have no idea what brands are better or worst than others. I live in Florida so it is hot and getting hotter. Babywearing is not very popular here so it is hard for me to get much selection in a store. Thanks for all your help.
