I have three girls Beau 3 Lottie 2 and Dora 1 and boy do they love to play and bark and then bark and play some more ..
Three times a day.. you can set your watch by it ..
It is usually Lottie and Dora the two younger ones and Beau will often now ignore them and come and find me for a gravy bone .. She used to sit and bark and then the others would start on her .. For her the barking meant 'hey I wanna play too'
As time has gone on they sorted it for themselves - if Beau wanted to play she will now instigate it otherwise she just ignores them .. If possible I would try and distract Missy ..
Its hard when you have three so young but things will calm down when they get to about
