Do you let your baby play in the sand pit? I believe they are very unhygienic.

I do feel it is unhygienic if the sand pit is accessible by dogs. Otherwise, I am perfectly fine for my kids to play in the sand pit, as it is a very great activity for sensory play. You can bring your kid to Science Centre's Kidstop. There is a sandpit which I feel it is quite fun for the kids and definitely safe and hygiene as compared to outdoor one. https://www.kidsstop.edu.sg/contact-us
