I bought a new orchid the other day

I used to be really good with orchids but something happened but what I don’t know. All of a sudden my babies started to die. After doing some research it looks as if they died because of water still left in the pot and that might be the cause. I think I started water them differently. In the beginning I was always watering them over the sink where I would make sure there were no water left in the pot but then I got lazy and just water them a little standing on the windowsill. So, due to this I bought a new orchid and I’ll do better with the watering and see if it will do the trick.
