My DH's family member has 2 DCs. Second just turned 1 and is, obviously, hard work, so she v ofter 'organises' sleepovers AT OUR HOUSE for her older DC, who is 6 and lovely, but I am fed up with looking after them! DH thinks that it is 'lovely for cousins to spend time together' ( they are not even cousins!), but our DCs are 14 and 12, so do not have patience or will to entertain their younger 'cousin' all w/end. DH just announced that the child will be coming this Friday and i have just texted the mother that we are going to see my family, so that will not be possible. Mother texted back that 'the child is very upset'. Honestly, I don't give a damn 😤 No amount of talking to DH helps, as he thinks that we need to help, but I have not received any help when I had young DC, why should I'help' them now? AIBU to say no every time from now on? My DC are not interested in having their little ' cousin' for sleepover, either.
