Personally I avoid the bay orientated stuff, as she'll get loads - if you really want to, give a voucher for somewhere like M&S or Mothercare etc where she can chose some baby bits herself, but get her something for HER
My best gift when I had DD was a big box of lush bath stuff, it was really appreciated in those early months to be able to have a break & wallow in scented heaven for a little while - I usually do the same now for other new Mums & always get good feed back :) -
the other great gift I did get, was a survival pack from a Nanny friend, she'd bought a big basket & filled it up with baby essentials, not the obvious nappies etc, but things as mentioned above -
metanium cream, teething granules, colic remedies, sudocreme, cotton buds, cotton balls, baby nail clippers, lavender aromatherapy oil, chamomile aromatherapy oil, epsom salts, big pack for adding to baby baths, natural soaps, shampoo, those muslin squares, scratch mits, skin salvation creme etc et
she also got me a box of cream cakes, which she brought to the hospital, would have been odd as I don't normally like them, but my God did i appreciate those when DD arrived & I needed carbs to help with milk etc
