jealous brother 😩

Anyone else dealing with a jealous older sibling? My littlest just turned 7 mo and my middle child is 6yrs and oh my goodness he is driving us up a wall with jealousy! He will take her toys from her and he will do anything to upset her. He could be minding his own business and as soon as she gets attention he's right there in the middle. He gets plenty of attention with and without her around and I hate yelling at him over and over but sometimes it's just ridiculous!
