We have quite a few carriers and each one serves its purpose.
Moby- amazing for tiny babies. So soft and snuggly and all around wonderful! But not so great when baby gets bigger...they start to sag and its hard to get it tight enough.
Babyhawk- LOVE this carrier. I've used it from birth to 3 years (during which I was pregnant). I find it extremely comfortable and easy to use. It's my husband favourite too!
Ergo- very easy to use. I find it hard to get a good fit...on the tightest setting, its still too loose. The back carries are better than the front for me.
Boba- this is my husband's. I think its meant for taller or broader body types but he loves it.
Ring Sling- Love for newborn and quick trips. If I wear it for too long, it gets uncomfortable. It's great for putting baby to sleep though because its easy to slip on and off.
Woven wrap (we have two...a shorty and a long one)- by far my favourite! They are SO versatile and incredibly comfortable. If I had to chose one, a woven wrap would be it. They do have quite a learning curve but it's worth the time to learn!
