a gift to show you've thought about it and been practical whilst being easy to sort.

1 gift bag, put in, box of nappies, box of baby wipes, baby soap, baby shampoo, tub of sudacreme, cottonwool pack of babygrows,pack of baby vests, bib set or a mixture of any of them essentials, everything there will be useful and get used,and they will probably have enough teddies and be grateful for some practical stuff, you could also add teething ring, rattle, babies first cutlery set, first plate and cup set, first hairbrush set, this wont be needed straight away obviously, but will show you have thought of the next year and again all will get used.

depending on how well you know the father, you could add in, as someone did to me, an "advice on vasectomy" leaflet and write on it "to save me buying all this shit again"

Mothercare vouchers, because there is always summat else they need, and maybe a little soft toy to go with em. Seriously they were the best received gifts we got!
