I'm not sure how many of each size i've got as I'm not that organised lol! But I've got a few newborn, mostly 0-3 and a few 3-6 as I like to be prepared for it all. Plus I've got my mums help so we both super prepared lol!
Frog99: Your best doing what you can afford, I'm not rich by any means but I have got a lot of help from my mum plus I don't go out and buy expensive baby clothes as they'll only been in them a few weeks. My fav shops are Asda George, Primark and Ethel Austins
Hats: they came with the sets I got, something like £8 in Asda for a baby starters set wicch you get: Bodysuit, Trousers, Tee Shirt, Hat, Mitts and a Bib.
Mitts: You can get 2 pairs for 50p in Primark, and as babies are always pulling them off and you lose them I thought it wa a great deal
Bibs: You need loads of these as someone has said babies are forever going sick. I was told to get about 50! Which I thought was a bit drastic. With my bibs I got a few from starter sets but most the them were from Primark, 10 for £1.
Cot Blankets: I got these now as even though the baby will be born in summer, they were hard to find and I wanted them in long before winter. Plus they were only £4 each in Ethel Austins
Socks: I've got different sizes of socks 0-0 and 0-21/2. I found that it's easier to buy in bulk, 5 pairs of socks for £2, saves money in the long run.
Cot Sheets: Like with other things your going to need a few of these over the course of your baby/child sleeping in there. Especially with accidents happening etc so best to buy in bulk
