Some of the things I remember:
Baby Gap is good for cardigans and much cheaper than JL.
With car seats, they've all passed the same safety test, spending more is usually just for the brand/colour. Most crucial thing is that it's properly fitted.
No such thing as the best pram - just the best for your needs, again price is irrelevant.
Her mantra was "baby doesn't know, baby doesn't care", so need for matching furniture, feeling bad because we don't have a nursery etc.
Some babies love being swaddled, some hate it so buy an absolutely basic pram blanket to try it out. If baby loves it, you can buy a swaddle blanket, if baby doesn't, you've got a pram blanket and haven't wasted time.
Recommend getting a washing up bowl rather than a baby bath, and then a bath support. Top and tail bowls are a waste of money.
Nightgowns with open bottoms are really handy for night time nappy changes.
She also recommended against cat nets over cribs and said we have to start training our (13 year old, spoiled, soft) cat to stay out of the bedroom :-(
