Should I start buying these things now at 20 weeks and do you think this is a good deal?:)?

I started to buy little things after my first trimester. it's easier if you spread the cost over a longer period of time but it's entirely up to you The shopping has gone mad though since I found out the pink things everywhere and only really a Dresser, the Cot, the Crib and you can never have enough nappies. :) This is bar the cost of decorating/carpeting the Nursery which isn't too bad. Start buying things when you feel comfortable.
