I need an outside opinion on this, so I'm hoping you all can tell me whether you think I'm being unreasonable or not.
BM requested SD over the long weekend for a minivacation, and DH ok'd it, meaning he gave up his time this upcoming week. Additionally, a year ago, he signed up for a race about 4 hours from where we live, that's taking place the next weekend. So he is giving up the following week's time too.
I guess it just dawned on him that he wouldn't see SD for two weeks, so he suggested that maybe he'd see if he could get SD earlier next week for a couple of days. I pointed out to him that we have two hospital birth tours scheduled, which we scheduled over a month ago and that I am having to take off work to attend. Both hospitals have stated that absolutely no children will be allowed on the tour, and both are scheduling a month out. So, if we reschedule, we're looking at doing the tours 2 to 3 weeks or so from my due date. I told him that I wasn't rescheduling, but that I'd attend without him of he wanted to have SD. The only sitters we have for SD are my parents, and they will both be working during the tour time, so that's not an option.
He then suggested that maybe we could bring SD to the race, and that I could watch her while he participated. I haven't given him an answer, but honestly I don't want to deal with that. The race will be about 4 to 5 hours, where spectators are expected to hike several miles, in the heat, at altitude.
I will be 7.5 months pregnant at the time and I'm concerned about how I'll handle it before I even think about adding a 3 year old to the mix. FWIW, I did the race 2 years ago, and I don't remember seeing any kids younger than maybe 10 at the event.
Am I being unreasonable if I tell him that I'm not going to watch SD if it means bringing her to the race? It's not just SD, I wouldn't bring my own bio child that age either. I want to do what I can to help DH see SD, but I don't feel like I should have to forego hospital tours or bring a 3 year old to an unreasonable location to do it.
Thoughts?

No. I do not think you are being unreasonable.
I think hiking for 5 hours, in the heat, at altitude may not be as much fun for a 3yo or a woman who is almost 8 months pregnant..
No way jose. I think that's an unreasonable request from YH, to be honest with you.
My DD is 3, and I wouldn't take her to an event like that. It wouldn't be fun for her, and it's not exactly quality time with dad.
Thanks everyone for the feedback! He works afternoons, but she is just in day care over the summer, so I'll suggest that he pickup her up for a morning activity during the week.
Thanks!
