Idk what to think of this my husband and daugher

So get this, I went to work today, and come home tonight, I pull into the driveway and see the TV is on because the dogs had moved the curtain, and I could see inside. The dogs start barking at the car and immediately I see my husband pop up and turn off the TV and he runs over to where my babys bouncer is and start putting on this big show like hes been playing with her... he said they had been playing like that a while, which I know is a lie because I saw him get up and turn off the TV. Now I dont know if he just ignores her while I'm at work or what... I never make a big deal about them watching TV or anything so I dont understand why he would lie... should I be concerned or is this nothing???
