Search for the best potty

My son has been getting ready to be potty train in the last few days and I have been trying out a lot of potty's ...

I tried the chair potty first ,he found sitting on it quiete hard .. And it left him with a sore bum ...
Next was the small poundland potty. In this he cried cause it led his legs becoming numb ..

Finally after loads of search I brought the car potty seat from argos for 14 pounds .. I was worried that this too could end in disaster but my excitement he loved the sponge car seat ,the smsll button which made the car sound kept him occupied. The seat fits perfectly , easy to assemble and clean ...

Behold !! Today my son pooped in toilet and I cant imagine how happy I am.. Its funny how when you become a mom how such silly things become important milestones in life ...
