I love the Hug a bub for the first 6 months...its really easy once you get the hang of it, i never found it to be hot or uncomfortable and Ds1 and DS2 have loved it!
Then an ERGO best thing ever! I wish someone would carry me around in an ERGO! lol!

Good luck! Can you go to a MG and try a few or is there an Mothers direct store near you? They have a few styles you can try!
Good luck !
