use ChuChu la... much better, I just Nuk before, but BB eat very slow and little... after change to use ChuChu, BB can eat more and faster. Also no matter how old is your BB, u don't need to change (milk mouth) but for others, there are milk mouth #1 and #2. The price of Nuk and Pigeon is much cheaper. If u want to buy Nuk or Pigeon, u can go to 護協, for Nuk bottle, there is a pack cost $78 for 3 bottles.
you better buy ChuChu PPSU bottle which is around $85/pc. And I heard from other mama... Jusco will have sales on this month end, and u can go and take a look how much discount you can get!
for bed, u only need to consider the layout and size. (As I think most of the design are the same. The most important part of the bed is the 床"肉". The one my BB using is too soft. And after sleep for a week, there is a head shape on it.. haha.....
奶嘴 - I use Nuk, but I see the layout of Avent is much beautiful. You can buy the one for your BB to test wheher he/she like it or not!
