My children are best friends they love each other very much. So when my in laws beg to take my oldest for a day. My youngest cries when she leaves. I put my foot down on them taking both bc he can't talk yet. My oldest tells me everything. Like when last time my MNL took her to the Halloween store and how she freaked out at the entrance. And for the rest of the week she had nightmares. My SNL plans playdates with people I don't even know, she came home with a new word"F*uck" and wanting to push everything around. Anywho, yesterday my SNL took my oldest to the pumpkin festival my young cried for 2 mins then was fine after his sister left . Now my SNL went to Facebook saying how my youngest always cries and never has fun and how he wants her more then me. Now the rest of my husband's family is starting to chime in agreement . I'm over it.
