I bought this because it's one of the few UK-produced titles to reflect a lesbian-parented family, and I do really like the way in which the family set-up is entirely incidental to the plot line (plus I love the illustration where Spacegirl and her mummies are all ill in bed together with all their various books/gadgets/cat etc. around them - very funny). But I find all that puking a bit much, especially given the extremely brightly coloured illustrations. It also seems to try just a bit too hard to be all-inclusively PC in terms of the people illustrated - it feels a bit like the illustrator has been ticking off a list of stereotypes/categories to include. This wasn't quite the book that I had hoped it would be, but I'm sure that my now-2-year-old will absolutely love it when he gets more into bodily humour.
Edited to add: I've now increased my rating to 4-stars, as my son (almost 3 yrs old now) thinks that the puking is absolutely hilarious, and his laughter is so infectious that you can't help but laugh along with him. I still find the illustrations scarily bright though!
