We are now 9 weeks sans kitchen and have at least 6 to go. Fortunately no infants (our 20yr old DDs are at uni)
Here are my suggestions:
Get 3 or 4 large plastic containers to store foodstuff
Buy a hot plate so you are not relying purely on microwave/toaster
Buy min amount of cheap plates/cutlery and glasses that you would not mind breaking rather than assume you can purely use paper/plastic plates etc
Stock up on dishcloths and cleaning sponges for washing up
Small fridge if poss
Buy lots of washing liquid
Microwave in bag rice/porridge. Savoury and sweet biscuits. Lots and lots
Paper towels and antibiotic wipes will be your new best friends
Bottled water supply at hand in case water goes off
Get a cheap folding table that can be used for additional workspace with plastic table cloth
Extension socket for use when/if you have to manoeuvre to different part of room
Last but not least...... Corkscrew!
