Just wanted to share the experience - and feeling of shock and guilt!
We nearly lost ds yesterday - literally!
I left the house very early to drive down to Leeds for a business meeting - it was pouring as I left. While dh had his shower, ds got bored watching him and wandered off - dh thought into the lounge to play with various toys. Having got out the shower, he couldn't find him anywhere in the house - upstairs or downstairs (we don't use stair gates as we've trained him to climb/go down safely).
He went downstairs and saw I'd left the outside door open (the heavy rain must have distracted me) - and as the inner door has a pane of glass taken out so that the cats can get to the cat flap, he thought "oops - ds has escaped!". He had a look outside but couldn't see anything - went back upstairs, searched the house again, looked outside again - still no baby.
Then he thought he could hear a cat - which (ours are Siamese) often sounds like a baby, so he went outside again. This time he could hear ds but couldn't see him.
Following the sound, he found him at the other side of the house next door - wet and muddy and distressed.
We think what happened is that he followed the the route that he uses when we walk him home from the childminder - ie down the driveway, turn right along the pavement and up the next driveway. Perfectly logical - but then he found he wasn't at "his" house! (Childminder lives the OTHER side). He wasn't muddy enough, we think, to have gone the "direct" route through the two gardens.
God knows what a car driving down the road (fortunately a very quiet one!) would have thought at the site of a 17 month old in a wee yellow sleepsuit, toddling along the pavement at 7.15 in the morning!
Dh got a big fright - but ds seems none the worse for it! As far as ds was concerned, it just seems to have been a big adventure. But for us, all the "what-ifs" go through your head.
Wheg I rang dh at about 7.30 and got told about this "adventure", for the rest of the drive to Leeds, I couldn't stop thinking about it - and again on the drive home! If something has happened to him.... and it would have been my fault. Dh went home in the afternoon - partly to get on with some work away from the office but also because the shock had hit him and he was feeling awful!
As well as now making doubly sure that we shut the outside door, we'll be adapting the missing pane of glass to make it more "cat" sized as opposed to baby sized!
On the funny side, apparently I did a similar thing at a similar age - turned up on my granny's door step minus nappy, having walked through a herd of cattle! But at least I would have been warm as it was in South Africa!
