sorry about MIL, that's tough. Makes it hard on the relationship sometimes and puts hubby in the middle. Hang in there and keep your chin up.
I'd suggest asking another parent take them and keep them until you return in exchange of returning the favor sometime or try and take them with you. If not because of the significance of the activities, maybe you could arrange a more convenient time with the breeder in which you can take the kids. Maybe if you stop asking MIL she'll get the hint. |
