Mommas most of you know I have 2 kiddos getting ready for baby number 3 due in March, they've been acting out and extremely jealous of one another and constantly fighting. Doesn't matter where they are. How do I help them get along? he's also always hitting her (my son is 2 and my daughter is 18 months) and throws toys at the walls etc. it's getting bad and we don't know what to do anymore.
