Don't worry Missus! We can help!
Don't know if you for some info already at your first antenatal but the bounty pack had some helpful bits and pieces.
I bought a pregnancy book early on, Your Pregnancy Bible by Dr Anne Deans. Not only had that got wonderful week by week info, it has sections on what to get, early baby care, pregnancy information, labour and birth, exercising pre and post partum... There was a free NHS one to but I found it hard to follow.
When shopping remember the first clothes last about 4 weeks so don't over do it.
You need:
Muslin cloths to mop up possetted milk (and if beat feeding in early weeks overspill). I bought 12, probably could have managed with a few less.
It is probably safe to assume a birth weight of about 7lb or more for clothes, better too big than too small. Mothercare's tiny baby is too small for most.
You need vests, I bought 10, a 5 pack in girl colours and a 5 pack in neutral.
I bought 6 baby grows, again, 3 girl, 3 neutral and of course was given a couple.
I didn't really but any pretty clothes for that first month, with the runny poo they do you're washing clothes constantly.
For sleeping you need a cot/basket and bedding. For bedding you want a mattress protector or two, a few fitted sheets. Then the top bit is a matter of preference and climate, blankets, quilt, swaddling blanket, baby sleeping bag...
Nappies (assume a typical weight of about 7lb as it puts you at the bottom of a size band) you get a few testers in the packs in smaller sizes and can do an emergency purchase of smaller ones if need be.
Either cotton wool and water or super gentle wipes.
A cream, personally I can recommend Bepanthen (called Bepanthol).
A changing mat with a washable towelling cover helps to keep the baby from jumping and waking when put on a cold one!
Baby bath lotion and skin cream.
A car seat or travel system.
Hope that helps you to get started! X

it's beating really strong now!
