DTs must of had a growth spurt as I have now discovered they can open the back door.
Got dt2 dressed this morning (7am and still dark) put her down to play, and as I was getting dt1 dressed I heard a distant cry from dt2, I thought she must have gone upstairs, but found the stairgate locked, went into the kitchen to find the backdoor wide open and dt2 stood about 50 yds away in the middle of the carpark.
She only cried because of the gravel hurting her feet, thankgod I had'nt put her shoes on which oddly I normally do, she would of carried on and it would have been another few minutes before I realised as I would have finished dressing dt1 first and put her hair up.
Thank god we dont live on a main road
