I have a 6 month old who literally screams every time I try to lay her on the ground to play or set her in the swing. She wants to be held all the time and prefers for me to be standing, moving around, rocking her. Is it possible she is "spoiled"? Sometimes I just lay her down if I know she is totally fine (diaper changed, fed, etc.) Maybe she is having other issues that I don't understand.... help!
