Question. Is the mother telling you she is ill or the daughter? Sometimes 8 year olds lie to get out of things they do not want to do. If her mom got her signed up with all these fun activities and she does not want to miss out on these things like camp, swimming lessons, baseball, whatever... she may be trying to find a way to be there for all the fun things she wants to do on her summer break. If I were you, I would stay out of it completely! Her mom and dad need to have a good talk about the summer plans and come to a comprimise that works for everyone. My husband never gets involved with my oldest sons dad. They are nice to each other and my husband is "dad" and does all the things he needs to do for my son, but he never ever gets involved with the decisions that his real dad and I have to make about visits, trading weekends, whatever it may be. You can be a sounding board to your husband, but he needs to step up and talk to his daughter and her mother on his own. Remember too, that it is not a competition who's house is more fun to be at this summer. You guys do not have to plan to do something huge just to lure her to visit. My son's dad does a lot more fun things than we do. He takes him to movies, skating rinks, bowling, arcades, rents his favorite video games, whatever Aaron wants. And we do not feel like we have to do more to keep up. Of course we do some fun stuff, but most of the time it is stuff you do not have to buy. We pitch to him, play catch, go on bike rides to fun parks around the neighborhood, set up the slip n slide and actually will go on it with him when he does not have a friend over to do it with him, take him fishing. But it is not a competition. Just be careful is all I am saying. Kids can smell out a situation and use it to their advantage:) They can manipulate. Even the sweetest kids you would not expect it from can lie to get what they want. congrats on your new baby! Have a wonderful summer!
