My friend's mom made this beautiful bracelet with my daughters name on it. I think she actually gave it to her for her birthday but it would make a beautiful baptism gift. It's been my most favorite gift she's ever received!
It wasn't this exact bracelet, but something like it.

Another, idea is I went to a christian store and found these hankies that can be used as bonnets. Then when the child is married you turn it into a hankie for their "something old" on their wedding day. It has a whole little story in it. I bought both my girls one of these on their baptismal day.
