We have a wagon so we don't have a boot as such but more space to put stuff!!
At the moment we have
2 folding chairs
A large pram
Nappy bag full of handy baby stuff
2 apples which escaped from the shopping and no one will bring in for me
Sterile dressings in packets from DH's leg operation in case it bled at home and which have also never made it into the house!
Worksheets from Erin's school
A frisbee for the dog not that the dog would fit in the boot at the moment
Some random items of children's clothing
Random pieces of tupperware
A picnic rug
Xrays from my foot surgery
Plastic garbage bags
A plastic fork
A baby blanket
Pencil case and colouring book
There could be more but I have already made 2 trips outside to check and DH is laughing at me!!! We could survive in the bush for days with whats in the boot if only we had food and water to go with it!!!
