Thanks ladies! I've got my MIL watching him this morning just in case, but do plan to take him since I feel bad asking them to watch him. (No idea why since my SIL leaves her 5 yo with them 3 days a week!)
Anyway, I'm very excited for my first meeting. I'm not sure what I think will happen, but I do think being held accountable for my tracking / weigh in will be good for me.
