Congratulations! I received my granddaughter just in time for Christmas - 22nd December. Knitting for baby girls is great fun.
My favourite source of patterns is Sirdar leaflets, they have some lovely modern styles. I've bought dozens from UK eBay.
Also, here are a few links to other patterns -
Ribbed Baby Jacket
Easy Baby Cardigan
I prefer the collared version to the hooded one in this pattern. The collared jacket knits up beautifully.
Zodiac sleep sack
Martin Storey's hoodie
Provence baby cardigan
Sailor collar pullover
If you haven't already joined Ravelry its well worth doing. There are many many gorgeous baby patterns on there, and lots of photos of finished projects that will give you ideas and inspiration.
