For each of our dgc we bought a Steiff teddy with their name and DOB embroidered on the soles of the feet. A bit expensive at £200+. In a spirit of emotion we got one for the first dgc and could do no less for the others.
For a token gift I order on line, the site might be "countryheart" , they do lovely boxed personalized wooden cards, plaque for door etc there are lovely and not cheap looking.
Also there is a gorgeous little book called...You Know How Much I Love You. It only costs about £5 and ends with beautiful words... to the moon and back.
