We have 2 dogs 10 and 7.
I came out of the kitchen to find a huge poo on the floor. HUGE and quietly steaming up the tiles. I was about to find a furry behind to place the blame on. After a second I thought 'that is not a dog poo' after a careful step I thought 'the dogs probably wouldn't take their nappy off first'.
My child has flung off his kecks and his underoos in gleeful abandon, squatted one out on the floor and run of giggling like a..er..mad...cackling...thing. If I'm very unlucky he may have peed in the lego box again .
The dogs never void in the house, never chuck dinner on the floor or save peas for Mr Lady who likes them more than me, always do what they're told, wait nicely at the curb, don't kick me in the fanjo or punch me in the boobs when they are on the bed for a cuddle. They're just very much more accomplished at being people than my feral child. They take a bath without complaint and/or ritualistic rubber duck sacrifice. They don't attempt free fall base jumping from the sofa or try and post biscuits through the letter box for 'the pasman'.
I love him dearly, we all do, he's very much part of the family...but things would be very much less stressful if he went somewhere that maybe had a field...or a tazer. AIBU?
We used to think we were quite good at parenting which leads us to believe this one might be a wrong 'un
