JoJoMamanBebe have got "baby Brother" and "baby Sister" baby vests in their clearance sale for £2 each. I've ordered 5 for friends having babies, they are bound to have a few of each sex! But thats loads cheaper than normal. Unfortunately they havent got the "big sister" and "big Brother" t-shirts to go with them but Mothercare do a version of those for £5 (Mothercare baby version vests are £8!!) Also I got free postage and packing even though my first order was only £4 - bargain.
