Hi mums, where can we take our kids where there's lots of open space and greenery, and they can run around?

Hi I went to Sentosa recently and there is this patch of very nicely trimmed man made grass field and the atmosphere is so good! You will have to get off at Beach station. I totally love this piece of open space. You can see the lagoon and it is not .crowded, perfect place for picnic. Another place is the Gardens By the Bay Kids Zone, so much space for the kids to run around. There is even a water playground inside and a cafe catered for kids. Somewhere closer to home will be Bishan Park for me. Can just bring a public mat and perhaps fly a kite. There is a Macdonald and two other restaurants in Bishan Park too.
