When the kids come home, have them take a few minutes to sit with her and give her some affection. She is excited because she missed them!!! Another thought may be to put the puppy in her crate or a gated off area until the children have had time to put their school stuff away and unwind a bit. Then when they are ready, they can have some play time with her!
Good luck!!
