Don't bother with
bottle warmers
nappie bins put them straight outside they stink after a while no matter what you do.
travel systems , a baby under 6 months shouldn't be in a car seat for more than 1+ 1/2 to 2 hours as it is bad for their neck back etc as baby sits up to high.it also puts pressure on their chest. leave the car seat in the car.
just get a good car seat
and a good pushchair.
Throw out Gina Ford books and go with what suits you + your baby
good stuff
muslim squares
john lewis sleepsuits suits have stratch mitts on them
Dummies saved me when my son cried with colic for 4 hours a night.
might not look great but they can always go , not like sucking your thumb or hand etc
good luck with your baby
just go with the flow
