I was going to post in AIBU but thought I might get better advice here.
I live with my dd (3) and partner in my very small appartment. He has three dc.
On weekends they come here to see their Dad.
Am I being unreasonable to believe that it is my daughters home and for them to play with her toys and sleep in her room they should at least respond to her when she talks to them?
They ignore her over and over, all I here is "(child's name) will you play with me please" repeated 10x. My daughter is the youngest and I admit that she does get excited when they're here and is likely to be a bit annoying in their eyes but it breaks my heart to hear her wanting to play and for them to look straight through her at the TV.
They will exclude her from other activities also, when we play outside with a football they will play games she doesn't understand, they will watch films too old for her etc, I really feel she is singled out in her own home.
I felt so sad for my daughter today I took her away from the situation and spent some quality time alone with her. Shes only 3 and doesn't understand why no one would want to play 
Am I over reacting?
