Mrs. H, I'm so sorry to hear that you and the little one is still sick. I do hope that you and your son will be feeling better soon.
As for the "disney dad", well...take what he says w/a grain of salt. He doesn't know how to communicate w/them and/or no what to say to them when he leaves messages. Also, it's his way of baiting you. Just listen to the message, shake your head, delete the message and then have a good chuckle because "disney dad" is really out to lunch and doesn't know his own sons. This is a man that knows one or the other hasn't been feeling well for quite some time and still tries to encourage them to be outside. Such a sad little man.
You are an excellent mother and I certainly wouldn't allow that message to bug me. There's always the delete key and you do have the power to hit it. Too bad we can't delete them from our day-to-day lives every now and then.
Please take care of yourself. Hugs to you today.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
