It definitely happens, White. When our first boy started school, prior to my OH being botted, he got a lot of invites to parties, play dates etc.
Once she got botted, these dropped off dramatically- fortunately, he was by then old enough to have the autonomy to go to his neighbourhood friends' places on his own.
It is one of the things that made me do as many of the school runs as I could for our second, as well as volunteer to take him to every event involving other parents. I did not want him to be a pariah among his mates' parents, although I wouldn't blame them for not wanting to be hunned to death every time he comes round.
