the more my husband is with his brother or family more than me, I notice I lock myself in my room and end up getting mad at everyone..... what if my husband would rather be with his family when the baby comes? when I baby sit a kid he absolutely loves he just sits there with his brother..... looks like baby is coming with mama everywhere =) I'm not complaining about that
