Indoor activities/places to take baby?

Hi ladies!! I’m not doing a party for baby but wanted to take her somewhere on her birthday that she’ll enjoy!

I was thinking of the Ripley’s Aquarium, but I won’t be able to use her stroller and being pregnant, she’s too heavy for me to carry the whole time, even taking turns with hubby. She doesn’t walk yet.

I’ve never been to an indoor playground so I’m not sure if they have things she would enjoy?

Any suggestions would be amazing🥰

Ps. I’m in Ontario, so if you are too, specifics would be great!
