I want to make a child kitchen out of old cubbards
Many, Many ideas here Debi!
Great idea. Make a sink, a stove and add some handles! https://www.diynetwork.com/how-to/make-and-decorate/decorating/how-to-turn-an-old-entertainment-center-into-a-play-kitchen
Cut out the top of one cupboard and sink a large s/s bowl or Washing up bowl into it. Use a large tray as the drainer. Use single cupboard as cooker and paint on the tials and hot pads. Another single would make a fridge freezer. A table and chairs and you have a working kitchen. Have fun!
Debi, here is a great set, I think, for you: https://www.hometalk.com/41568751/build-a-beautiful-play-kitchen-set-ez
