Does anyone else’s kid have done this? 😂

My son just turned 4 this January and lately he’s been sitting on top of me saying “ sister or “ a sister “ and he’s been doing it, it seems like everyday all day and I find it weird lol I took pregnancy tests so not pregnant as I know of anyway. He seen videos I assume that might mentioned siblings like coco melon but just find it strange that he does Pretty much all day everyday when he has a chance lol
