Things to do with baby

[Littlelegs19]

Hey ladies,

I have a 4 month old son and we currently attend heart beeps classes once at week in bexley village which we love but was wondering if any mums can recommend anything else in the sidcup/bexley/bexleyheath area for me to do with him?
I looked the libraries website but everything they do is too old for him at the minute.

Thank you
