I'm sorry but a tap on the legs is not beating the crap out of them, and if they hit you how the hell do you reason with a two year old, to me I f they hit someone they must realise that they will be hit back otherwise they will have a shock later in life surely, and I do t want this to descend into a hitting your kids thread please.
I spend a hell of a lot of time with my daughter as I'm a shift worker probably more than most dads who work 9-5 jobs, she gets more attention than most kids I would think in this time, it's just the frustrating side of it all and apparently the worse is yet to come when they are teenagers!!! What the hell have I let myself in for lol.
