Beautiful card Jay. Unfortunately we don't have that luxury of being naive about pregnancy, we're just too well informed about all the things that could go wrong during this process. Actually it's one of the reasons I'm leaning towards not doing this again - I don't know if I could handle another year of this stress!
I think your sister's attitude sucks quite frankly. Just because your niece is very young doesn't mean she doesn't need to be aware of the same things you do. There might be a few more risks being an "older" mum, but there's really not that much difference. In some ways I get the opposite attitude from my sis. She seems to think she's the primary authority on pregnancy and motherhood because she has 4 kids, and thinks I've been far too wary throughout this pregnancy. Just because her kids have turned out "fine" she's ridiculed my choices to stay away from sick people, stick to the safe food guidelines and haven't touched a drop of alcohol. I can tell she's going to **** me off even more when it comes to our parenting style and choices.
