I used to have the normal size table and booster seats on chairs and a highchair. I hated it!! Had to lift all the kids into their chairs and then out of, the highchair took up so much room and the booster seats were a pain to clean.

The table I have now is the perfect size! They can all get on their own chair, they are easy to clean after every meal and if I need to sit with them, I either sit on the floor or on one of the chairs I got from a school. It's a kid sized chair but with metal legs. It supports my plus sized butt just fine

It's all your own preference but I highly recommend child sized table and chairs. I have back issues and this has helped! I have thought about what happens if I take a young child again but I kept one of the booster seats just in case!
