I'm cool with babies being tied to the cribs, with the addition of infants. We haven't had infants in any iteration of The Sims, so I'm happy to see content that is pretty much exclusive to The Sims 4. & infants in my opinion are close enough to newborns...as they can't do anything on their own, like walk & I think I read something where they cant even be fed in high chairs until they learn to sit up. So, it seems like infants are around 5-6 months old range...& since they're playable, I think how they've aligned babies, infants, toddlers seems cool for me. But I guess I'll have to wait until next week when its released to see.
