I love the Rainforest collection by Fisher Price. I have the baby bouncer, the swing and the jumperoo.
Bouncer - I found the bouncer to be the most useful when my baby was first born. It was suitable from birth, and provided a comfortable and safe place for my baby to sit while I cooked, cleaned or showered. After a few weeks he started showing interest in the waterfall, and eventually started to hit the little toys. The only down side to the bouncer, is that it uses a lot of batteries if you're using it with the activity bar. My baby is now 4 months old and we still use it for nap time. He refuses to sleep in his crib during the day, so we put him in the bouncer, bounce it, and he'll be asleep within 5 minutes. The seat cover is removable, and washes well.
Swing - The swing is awesome for the same reason.. it can also be used from birth. It can swing back and forth, or from side to side, and is great for when you need to cook dinner or do some housework. I love that you can plug it in too, so it doesn't use up batteries like the bouncer does.
Jumperoo - This is my son's favourite toy by far right now. He'll sit in it and jump for ages.. then eventually he'll pass out, exhausted from all the jumping! He's always figuring out how to do something new with it.. he's recently learned how to spin the wheel to make the animal noises.
The whole collection is brightly coloured and fun. Also in this collection, is the highchair, the activity gym, and mobile, which I do not have, so I can't rate them!
