Would I be allowed to bring a kilo of cheddar cheese into Thailand for my own consumption? Are there restrictions on such foodstuffs? Thanks.

Oh wise tribe... My family is spending a week in Thailand end of March. We're coming from Singapore. Do you know if I can bring in some unopened UHT milk and home baked breakfast biscuits? My toddler is very challenging to feed and these are the only things he'll eat for breakfast; without these he gets terribly sore tummy aches. As a New Zealander, I'd never dream of packing any food whatsoever, but thought I'd ask in case it's ok? Would make things so much easier!
