Firstly, I love my DSD and I'm so pleased that she doesn't feel pushed out and is always so excited to see the baby. DSD is 8 and DD is 5 months.
However, DSD is off school quite frequently with different illnesses (D&V last week for 3 days, a bad cold the week before for 2 days and a temperature and pale face the week before that) and when DD was 3 weeks old and just out of neonatal, she kissed her all over her face and gave us all the most god awful cold.
With most things I try and see it like DSD lives here full time and is my full biological daughter to do the right thing by her. For example we have 3 bedrooms, and although DSD is only here once a week (her choice) she has the bigger bedroom out of the two girls, even though we really really need the space. Because if she was my DD and here full time, she would have that bedroom.
However she keeps kissing her on her lips, sucking her dummy rather than sterilising it and then giving it to her, trying a cucumber stick with her but sucking it first etc...
I really don't want to upset DSD or DH (DH is more likely to kick up a fuss to be fair) but I feel I need to protect my babies privacy!
I don't think I'm being unfair here but opinions welcome.
