i couldnt live without

bath thermometer
mosquito netting for pram ( always good when at MIL for dinner and it bbq)
baby monitor
nappy sacks (great for wet clothes, mushy bikkies etc..)
travel container for baby wipes ( the huggies one with pop lid in middle)
if you cant breastfeed, one of those containers with 3 spaces in it and pour lid for formula ( saves making milk and having it spoil)

good luck and have fun shopping!!
