We watch my 1 1/2 year old niece a lot. We had her all afternoon last weekend, Saturday and Sunday. Well my brother in law texted my husband and asked for us to keep her over night this Saturday. We said no cause we want to spend alone time together. I'm ovulating this weekend and we are ttc. Well my mother in law was just here and kind of made me feel guilty about it. Cause I was joking around the one night we had her and said "do you want to sleep over" and my mother in law was like maybe since you said that he thought you didn't mind. I was like I don't mind in the future but we haven't spent any time together. And she kind of just shrugged her shoulders. How would you feel about this?!
