I only have three kids (with big-ish gaps between then (5yr gap then 3yr gap).
There's such a massive 'trickle down' of bad behaviour from eldest to youngest AND the eldest doesn't get why we want to try and ignore some of the bad behaviour in the younger ones. Middle one doesn't get it either, though it's more understandable.
Mostly they are lovely, but the dynamic can be very difficult. We realise they are in competition for our attention but I cannot seem to make it work at the moment. The eldest is volatile and throws things/stomps off/huffs [has given up hitting things and people now but does a lot of shouting]; the middle one hits, dissolves into tears, tells tales; the littlest is now picking up all the bad habits...
We're trying to teach them co-operation and problem solving and sharing and being a team - but the age gaps and different interests make that hard.
So. How to give them more positive attention, ignore what can be some pretty aggressive stuff (you can't ignore hitting, surely?) in these circs...?
