No, but we are starting to consider it.
Yesterday, after the surprise snowfall during the night, DD woke us at 6am or so to ask if she could "get dressed". This question in itself should have raised a between the two of us, but didnt.
Turns out, she got dressed, put her shoes and coat on (she's nearly 5 yrs), then put a a coat and shoes on DS (nearly 3 yrs) who was still in his pyjamas.
They BOTH went out the front door, leaving it open !!! to play "snowballs". They came in some time later when they were very cold and wet.
Top bolt on front door has been used since.
