Hi mummies/daddies!
From our experience we do have some good experience with the below venues for kids parties:

The Colonial @ Scoots

At the same time, if you are running out of ideas for venue booking, i strongly recommend this site for browsing of available spaces in Singapore:
http://wearespaces.com/. Browse and send enquiry, that simple! At the same time, if you are staying in public housing, CCs have some very good spaces for booking!
For party entertainment wise, we do offer party packages as well and you can click
here to view, which are affordable and fuss free. Catering wise, stamford and neo gardens are really good options that have special full month or first birthday themed catering. Feel free to contact us if you need any more advices!
