I think it really depends on the baby. DD absolutely hates the bubba moe now - but she was fine in it for the first couple of months. She goes better in upright things now - like an ergo. She has silent reflux so doesn't like the fact that you have to lie them down in it.

I did buy mine when DS was 14 months old to carry him around - and I think its brilliant for that. I dont' regret buying it because I can still carry him around in it now at 22 months.
