I'm buying my DD Ella and one for my bub-on-the-way a gorgeous crystal Christmas tree ornament from Swarvoski Crystal this year. They have a good selection- and baby appropriate ornaments too. Ella was given a bauble with her name on it last year - so my plan is to buy a special ornament for each child every year and keep them in their own special boxes. Then as they get older they can place their own ornaments on the tree (we had something similar when we were growing up and thought we were so special with our own things and really treasured them).
