Also a little presumptuous to assume the OP speaks Afrikaans just because her parents currently live there, unless the person knows OP, in which case, why post a rather generic reply?
And for the OP: I think your decision to have your parents and in-laws stay out is the way to go. Looking back it is what I should have done and what we will do going forward when parents visit. Gives everyone some space and down time while also giving grandparents plenty of time with the little one. Also, if you really need a break, just tell them that you need an afternoon to yourself. If they are at all reasonable they will either already know you need some space or accept that you need a short break since you asked for it. Good luck and I think you're approaching this well. While it is only 2 weeks, the couple weeks my parents stayed with us were probably the longest of my life and I wouldn't repeat it, at least not in a HK-sized home.
