Do you put them in a pack n play? A bumbo seat? Their car seat? Their stroller? A baby carrier like the ergo?

How did this change as they got older?

I'm debating about whether to register for a pack n play. Our house isn't that big though, and some of those are just HUGE! The smaller ones, that would fit in our kitchen or living room are only safe up to 15 pounds, so it seems like a waste of money for something that will only last a few months. I'm just at a loss as to where we can put the baby while we're cooking or cleaning, aside from their crib.

ETA: We have two dogs, so baby needs to be out of Fido's reach, lol, lest they think baby is their new toy!
