Re: best for a 4 month old who HATES being worn
Four month olds are hard! They want to see everything that is going on, but they aren't big enough to see from a back carry position in any of the soft structured carriers and being on the front just isn't as much fun for them, IME.
I like to wear babies that age in a high back carry in a carrier that I feel comfortable putting them in and getting them very tight and secure. This could be a wrap or a mei tai, but if you don't have any experience with wraps I think a mei tai has a much smaller learning curve.
Knowing what you have tried and not like and why you feel that your lo doesn't like being worn would help with making suggestions. But, when mine were that age they were happy if they were up high and could see.
