Get the Ergo baby carrier. It is one of the best carriers and everyone I know who has it love it and you can use it for kids up to 40 lbs. The carrier puts the weight on the hip so it is not too hard on mommy/daddy's back and it is extremely comfortable for the baby to sleep in. For infants, you need to get an insert too. You can get it at Fab Baby Gear, maybe Kiddy Town too. It is extremely useful, we use it all the time.
可是这个好像国内当当网上有卖的。baby einstein 的 DVD,内容超简单,但宝宝们超喜欢。大一点的孩子就有little einstein DVD.
