I just remembered a few other things!

DD spent a bit of time in her Maclaren rocker too when she was younger. It has a toy bar so I use to rotate the toys from her jungle gym and she'd happily sit in it for a while swatting her toys.

I also have a Fisher Price Jumperoo which DD started using when she was about 4 months old (when she had good head and neck control). She still loves a good bounce in it and it's been a saviour on many occassions - especially now when I want her contained (and she's in no mood for her playpen!). I highly recommend getting one or an exersaucer/activity centre at some stage. They really are amazing.

DD also has a Fisher Price activity table which she loved even before she started standing as she could reach the button to activate the music from a sitting position! An activity table that lays flat and then converts to a table or walker would be a good investment when your DD starts sitting by herself.

Last, but not least, the old Jolly Jumper is awesome. We got one for free so we used it outside. DD loved bouncing around in it and looking at the breeze in the trees and the birds flying around. I personally prefer the Jumperoo as it has toys attached to it and plays music and is more comfy so they can spend longer in there. It wears them out too so they tend to go to bed easily after their 'work out'.
