size 0000 and 000 baby suits!
Portable change mats
steriliser (just boil water in a big saucepan)
bibs! (Not until they're older)
very useful things:
Good sturdy pram that converts from bassinet to toddler seat with good turning circle
baby carrier (single mum that had to hike up 6 sets of stairs with groceries and all other luggage plus baby!)
old-school cloth nappies (still use them for cleaning up accidents, SO handy!)
wipes - galore!
My DS was a very clean baby, never vomited, soiled or made any mess. Til now, he's 3! So just buy barest minimal clothes until after hub is born! Can not stress that enough!
