What to buy a 1 mth old baby girl for xmas?

Has anyone got some good suggestions as to what I could buy my one month old girl for xmas? I've bought her so far a few books and a jolly jumper (although she won't be able to use this for a few more months). I know she wont have any comprehension that its xmas but i just feel like I should get her something more, particularly since her older brother is being spoilt rotten.
