What the heck do I get them for Christmas?? Is it cool to just get a boat load of toys and stuff for lil William?
Eh, you know with a new baby your house is filled to the brim with baby wrangling equipment. So lots of new stuff isn't always best.
I'd get one good symbolic book for the future - either a fine illustrated Robin Hood (say), or a cool board book (see Boynton recs above).
You know what helps, though? Any kind of housekeeping services you can offer or pay for. Like...paying to do the laundry. Or buying some easy-to-heat meals at Trader Joe's, or make a big lasagna. Because it's very hard to do the basic life maintenance stuff when you've got a breast limpet on you 24-7.
Also, just going over and holding the baby while Mom takes a shower is very nice and helpful.
