It's worth also mentioning that you will be wearing your maternity clothes for a while after the baby arrives as it does take some time before you can fit back into your 'normal' clothes - some times months. So it's worth investing in the basics like a good pair of jeans and some casual tops you feel comfortable in.

If you do go for a shopping trip to London, also check out Blooming Marvelous and the Mamas and Papas store on Regents street.

Another great website I used when pregnant was Bras4Mums, they have a great range of pretty bras in all sizes and they are not too expensive. I'd skip the 'maternity bra' and go straight for a nursing bra, you'll get more use out of it that way. I'd also recommend some bra strap extenders, they cost a couple of francs but are really useful.
