Throwing a fit

Terri

My girl just started this. When I try to put her in the pack n play or when I lay her down to change a diaper. She cries, she yells, kicking her legs, waving her arms, throwing a fit, then she chills out after I tend to the reason I put her there. But I'm just like wtf?! Is anyone else's doing this? Is this the next phase in her learning?
