Just need some advice here please . My other half moved in with me and my children . He has a child from previous who he has 50 percent of the time . My youngest has a severe weakness in her chest and is on asthma medication . Three times this month he’s child has came to my house when unwell and made my children all unwell and requiring the youngest to be hospitalised once through becoming unwell . On Tuesday child came round again when I was assured it was just a cough but child was very unwell , I had to try and keep my children away and my vunerable mum who lives with me . Child is expected to come here tonight and stay until tomorrow afternoon and come back Christmas Day Until Thursday, I am concerned about everyone becoming unwell again . Just for reference I adore my stepchild and do everything I can . Just wondered if anyone had some thoughts on what they would do in this situation . Thank you
