A bit early as from memory there are sales around June (can anyone shed any light?), and all our Reception new starters will be growing like mad no doubt between now and then, but it's nice to have this to think about now the places are allocated for most.
My DD is very small so though she'll wear trousers (which she prefers to dresses generally) she needs her own new ones plus DS trashed his polos entirely so she'll only really get his old jumpers that all shrank a lot anyway.
They wear plain coloured t-shirts for PE and I found some in a 3 for 2 at Boots together with plain shorts so I got her age 3-4 which is pretty huge on her anyway!
M&S do 100% cotton trousers and they are OOS in her size but I'm assuming they'll be back in stock fairly soon. 100% cotton polos from Matalan are extremely reasonable!
I'm still going to be hunting for 100% cotton non-PE shorts for her I seem to remember from DS Reception days (he's still wearing that pair). Both of them seem to get quite itchy in non-cotton trousers.
Unfortunately DD is still not potty trained properly (we are seeing the continence nurse again next month) so it's going to be a case of sending at least 2 spare pairs a day and washing daily I fear.
But for DS we had 4 pairs of trousers to last the week (they wear their PE joggers all day on PE day which helps) and 6 polos as they come in packs of 2 or 3 anyway.
Despite what the optimistic posters on another thread think, we also needed more than 1 (2 or 3 worked OK) school jumpers/sweatshirts.
I'm happy to say that the amount of food and paint on DS' tops has reduced in Y1 but the amount of whiteboard pen hasn't and I still can't find any way to get that off!
