I'm with ausgirl. I have had a lot of these cards over the years, and they are all special.
The one I remember most said "Digger truck car bus digger." which were the only words this little boy used to say, and then his mum had written "What X is trying to say is thankyou so much for all the special care you have given me. I will certainly miss you!" and they gave me a photo frame, which is stunning and up in my lounge room

So, yeah, make it personalised, with something that your DD does or says. Another family at the same centre gave me a photo of their child wearing this annoying singing bib that I used to always joke about with his mum.

So thoughtful of you to give them anything, they'll love it for sure.
