jesse,
i have two allerhand bags which i bought from a mummy on the forum. the carry on bag is very expandable (like doreamon's pouch), so i use it to transport my breastfeeding stuff to and from work. it's super heavy though, cos i tend to overpack it. have a grouse -- bag has quite a few metal parts, and according to the website, the bag's not machine washable. mine's pink and quite dirty already, so am contemplating just throwing it into the washing machine ...
my other allerhand combi cooler is used in the evenings and during the weekends when i bring bb out. one compartment for my personal belongings/extra change of clothes, and another for his porridge/water/snacks. i've washed this in the washing machine twice already, cos a lot of bb food always lands on it during meal times.
you can find allerhand products at taka and isetan. it's great singapore sale now right? they usually have 20% off allerhand bags during sale periods.
