Yes, I've used exersaucer before...it's great when I have to keep the child with me as I prep meals, or when the bigger kids were involved in active play.

But this time around, I hope to focus on infants and toddlers (8 months old to 3 years old)....if I have two that are close in age, it would be nice to have them together in their own space to interact with each other.

I saw some gates (surround-something) which will be ideal. And yes, shelves are practical to section off space.

Thank you folks for your support! We are investing quite a substantial amount to this business - it is however a practical solution for us to get back into it - so you can just imagine the anxiety involved.
