Baby Rockers question

Hi all,

I am new here, I am ready to pop lol (8 months pregnant) and trying to get things ready for my little bub( it's a girl!!), anyways i am wondering if i can get some feedback on baby rockers ?

I am a little confused in terms of sizing and what brand i should get, i was looking in google before and came across the Fisher Price Baby Rocker but as i live in Australia i cant seem to find any stores that stock this, i would maybe like 2 of these ( one for a friend who is also pregnant) but the shipping costs from amazon are a little high for my budget.

If anyway could help find a store in Aus that stocks this baby rockers i would be very greatful, i am kinda hoping there are some other aussie mums in your forums, cause all the other forums i am active in are mostly people from overseas.

Thanks in advanced for any help, Lisa
