A nice blanket? My 2nd received a lovely one from jojo and still has it on his bed today... (he's 4 now)
We also loved and still use today a personalised towel..
A nice framed picture for the nursery/bedroom? (Thinking Beatrix potter/ Winnie the Pooh characters type of thing)
Books? We had plenty from the 1st born, but the favourites were battered, so nice to have some new ones for 2nd born...
