I fully agree with Jol1960. Giving positive attention to a badly behaved child gives mixed messages, and they learn bad behaviour earns them good attention. I've seen this go very wrong, not at all a pleasant outcome for the younger sibling. They need to be taught, abuse for attention is never right, regardless of whether its Jealousy or otherwise. Children grow and they up their game. They learn how to manipulate. It can be the cause of a lot of resentment & anger in the younger siblings. If it doesn't, you've been lucky, but I've seen the outcome of this. I.m not talking punishments here regarding the older sibling, but firm boundaries & age appropriate consequences, it's never okay to hurt a baby, regardless of age.
