I am not sure then. My daughter is 3 years and half. I also saw lots of babies in their carriages in the Biodome. Your daughter is free, but you have to pay around 10 dollars for one adult.
Well, according to the poster in the metro station, Biodome with the image of Caiilou ends this coming Sunday, that is three days away. My daughter and i went to the Biodome last Sunday. It was true that there is a big Caillou and some activities related to Caillou. Many kids were there, and fish were wonderful thought not of a big variety. May you have a good time with your child.
