I have both

The bouncer makes it easier so you can sit the baby in it so you can get things done. I didn't get a swing until my daughter was about 2 months but it really helps put her to sleep.

I've heard wonderful things about them helping babies sleep or just relax. I'm definitely investing in them for my twins.

my son hates his swing lol. He's 5 weeks and I still can't get him to like it. he likes his bouncer but he doesn't have enough head control yet so we just use his rock n play and his play mat on the floor as of now

It helps a lot when you need to put them down for a second so they can be in the same room as you. E loves his bouncer!

My daughter barely used her but I'm getting one for this baby cause I know every kid can be different

Not necessarily but it was a life saver for me, my son loved and still loves he's swing and bouncer
