yes bodysuits are essentially vests for the baby but with poppers under their bottom, they help hold the nappy in place! and you will get through LOADS of them, my ds4 still wears them and he is 2yrs 4mths!
i would say what hmmsleep said, but more than two hats, i tend to keep some spare bits for baby under pushchair, in car etc, so that we arent caught short if they puke/poo etc and also its good if when you go out you take a spare top for yourself incase baby is sick on you etc
i have been given a lovely snowsuit thing for in the pram but it doesnt have legs its just a sort of cocoon on the bottom half but with a hood and arms, much easier to get the baby in and out of. and i agree totally re cardigans/little jackets etc, they are lovely but i try and get the ones without hoods, as babies spend so much time lying on back in pram/carseat etc and i just dont think they can be comfortable lying on a scrunched up hood. same goes for babygrows that do up at the BACK, honestly not only are they a nightmare to do up, but i dont think they can be very comfy for baby to lie on? but that could be just me?
as for nappies i only normally buy one packet of newborn, but i have big babies, maybe get two packets in but you can always send your partner out to a 24hr tesco to get nappies!
as they are winter babies little socks and booties will be good, i used to put socks on underneath the boys babygrow, as then they would stay on and just helped keep their feet warm, as little baby feet (and hands) can get very cold easily. infact you can get little trousers for babies that have feet in as well, they are very good, i think mothercare do them quite cheaply in packs of two?
but mainly new babies wear babygrows! and lots of them.
OH i know get some of those nightie things for night time, they have sleeves but then no legs, just a long gown with elastic at the bottom so when you change babies nappy in the night you dont need to be fafffing with poppers and getting legs in and out of a babygrow! MUCH MUCH easier, pumpkin patch had them on sale for £3 the other day? and i know mothercare sell them as a pack of two for £10. honestly they are fantastic!
right i am off to bed, it would appear that baby must have grown as all of a sudden i am feeling a LOT more kicks, which is lovely, but sometimes takes me by suprise. hoping that the madboys will feel their baby sister kick soon, they are so excited
