My MIL is due to visit this weekend to see our 4m DD (and us!) but on the phone last night she told my DH that she has yet another chest infection I think it's about her third this year. The doctor has given her antibiotics again and steriods. She smokes a lot and we had already planned to insist she washes her hands at the very least before coming near DD but preferably changes her clothes etc... DH's aunt thinks MIL shouldn't come because of the chest infection but MIL is still planning to come. DH asked me if I was happy with that as if we're not he will put her off. We aren't sure - the problem is my DH works in retail so rarely gets 2 days off together it's not clear when the next time she can come will be, she seems to permanently have a chest infection anyway and to be brutally honest she lives to see her grandkids, they are what keeps her going. Aside from visits of this nature she has very little to occupy her and has been looking forward to this for weeks. She's a lovely woman and won't come if we aren't happy but she says she's just planning to watch DD on her playgym etc... so not too much contact. Should I say ok come? If we say not to come she'll be very disappointed. I'm unsure what would be for the best.
