I think from memory week 2 was half term though - he may well have been alright to go back one or two days earlier possibly, but it was good having the full 2 weeks.
also infection is a bigger risk after adenoids than tonsils because you just have a bigger wound (and the adenoids have a function of blocking germs coming down the nose so you lose that)
it was a great thing to do in all for DS though, completely fixed his hearing 100%, made his speech clearer, his eating easier, and no more sleep apnoea...
