Sorry but it happens even without kids - animals distract you too, as does weather, a visitor/phone call..
Life is just like that and I reckon those with kids are probably the best organised at dealing with it - I used to manage a full time plus kind of day job plus a stud of 20 ponies, 2 training courses and a few hobbies and a minor social life - now I can't organise myself to get a pint of milk from a town 3 miles away cos I find a break in the weather and decide to go for an hour's walk, get back and have to re-stoke the fire, go out to feed animals, come in and have the kettle on and then realise I totally forgot to go out for milk
