Tegam it sounds like your doing all you can. I agree it's not right you have to walk on egg shells. You should be allowed to tell everyone about how your children are developing. I know its hard for LTTTC but when they eventually do get
pg, they would yell it to the world. Every mother has the right to brag. You sil should just be happy for you. It's not ALL about HER struggle. I know I'm sounding heartless again but as far I'm concerned everyone needs to make allowances for everyone. Its a 2 way street.
I can tell you now it hurts me that my sister is having troubles but at the same time I know she would be upset if she missed any achievment my

Sometimes you cant win

Hang in there
