Every time I go to stand up my 15 month old face plants into my stomach. I have a contraction every time she does it... I smacked her diaper the last time cause I almost threw up when she did it. She just looked at me like I was stupid and kept playing... I am praying she mellows out before I have this baby because I'm terrified she's gonna end up hurting him. 😶😶😶
