I'm currently pregnant and in the middle of July myself, DH and DS are due to go abroad for a two week holiday but it will be when I'm in weeks 37 and 38 of my pregnancy.
I'm not going to go (obviously) but I have told DH to still go with DS as it's cost us quite a bit of money, which we wouldn't be able to get back and I don't want DS (aged 3) to miss out. Plus the thought of having the house to myself for two weeks in the latter stage of pregnancy sounds very appealing 
I mentioned this to my sister last night who was quite horrified at the idea. She was giving me lots of 'worst case scenarios' of me going into labour in his absence etc but I genuinely can't get myself worked up about it. If that happens then it happens. If it's relevant at all I'm due to have a planned c-section about ten days after they would return.
Am I mad to be ok with DH still going? My sister's reaction shocked me
