DH isn't even here - he's at a wedding abroad, left on Friday afternoon and due back late tonight. The plans are with his parents - going to their house for the day with the kids. The problem is that DS2 (7 months) seems to be going through some kind of sleep regression - I didn't sleep much on Friday night, was up and down lots last night, and I'm so tired I feel like crying. I don't drive (not that I would in this condition) so if I go I can't leave until either FIL or SIL is ready to take us home. So WIBU to tell them I'm not up to going? I don't know how they would react, but I do know DH will get the arse if I cancel - he sees family get togethers as Really Important.
