Love the pics Mellie, the ubiquitous pink drives me mad too! :)
BabyC sounds like you had fun at SantaLand.
Woowa you brave woman, good luck with the teens!
Sugar, it is always best to put children in a vest (baby version is t-shirt thing with poppers), especially in cold weather, as the layer close to the skin provides a layer of trapped air that acts as insulation against the cold. For our babies this will be important as they are being born in winter.
I had DD in the summer so once she got older she spent certain days just in the popper vest as it was 30+ degrees in her room. To know how warm your baby is check their belly, if it is warm they are ok, if hot they may need a layer removed/be unwell, if cool add a layer. Babies cannot regulate their temperatures like we can, so when indoors/on buses etc... make sure you check and remove layers if neccessary.
You may want more than one pair of mittens and more than one hat if you don't have already, they tend to go awol.
Don't buy too much newborn size until you see how big baby is, my DD being 8lb was only in newborn stuff for a week before moving to 0-3 months!
If you buy cute outfits go for one in 0-3 months (they poo so often that any fiddly outfit involving tights is a no no, plus until belly button is healed loose fitting items should be worn) and several in 3-6 or 6-12 month age.
Have you got muslins?
