So funny that your DD keeps tabs on your interactions with the boys, I'm sure she doesn't miss a trick! My middle guy isn't as upfront about his jealousy...instead, he just acts out suddenly, throwing toys or tantrums out of nowhere and then I realize why... Sigh. I'm sure there will be a day that they don't care how much attention we give to them, I just tell myself that so I don't get too frustrated.
Hugs and love to you and your kiddos!
