have a dd, 4.5 yrs and ds,2. both are gorgeous individually but together they drive me insane! is this normal? they adore each other and start physical play which always turns into wrestling, hair pulling, squeezing etc At what point do you stop this? don't want to stop them from touching each other but i literally cannot leave the room for one minute without screaming. any tips or advice? am definatley not the parent i thought i would be - thought i had boundless patience but i was wrong!
