Like I said earlier Kanda.. my two have been pretty good. We are out and about a lot, just me & them It's just the usual sibling rivalry at home that's a pain.. but you know what.. I reckon you'd have that whatever the age gap LOL. Mine are really starting to play really well together.. it seems to be getting better every day now. Once they're tired and irritable they fight & carry on, but I don't think I'll ever regret the 19mth age gap
