We have one but have n't used it that much. Does provide somewhere to change though, a surface to play that isn't like walking on hot coals and a non-sandy place to store stuff. Probably not worth it if baby is mobile or if you have a buggy with sunshade where he can nap (Europeans often drape a muslin or light blanket over hood to toe to provide extra shade).
Jaybee, didn't think Anthisan was suitable for under 2's.
Have fun
