All I can think of is carriers (Im carrier mad atm! I have a close baby carrier coming for DD3, have a soft structured full buckle carrier for DS and DD1 and now am hoping to get a beetlebum or kleinsmeikker for going out).
All I have bought for #5 is a glider chair second hand and Im getting the obvious car seat. I loved having NB Maz covers with their names on the back. I treasure them and will be keeping them for them to use on dolls/bears etc as they get older.
