hi, im taking my 5 week old DS for a long car journey tonight (about 5 hours) and wanted to take some EBM to give on the way. I wanted to know how much approx he would need - i expressed 2.5oz this morning but have another 2oz in the freezer if i need it..also how long will it keep for in room temperature - is 2-3 hours ok? and is he likely to take it without it being warmed up? so far i have given it straight after expressing so its already warm
thanks
