zampa I'm the same, I will be 36 weeks when I do my NCT class. If we happen to have the baby early then that will just be too bad (I think the NCT lets you change to a postnatal class if you miss yours because you go into labour early anyway). I'm assuming it's fine, a friend of mine tried to book onto a class and they told her it wasn't appropriate for her, timing-wise, so I wouldn't worry.
I went and checked out a nursery nearby this morning and absolutely hated it. It was perfectly fine, all the kids seemed totally happy, I just had an immediate "no way am I leaving my baby here" gut reaction. It was my first one though so maybe it was just a freakout about having to make what feel like these huge decisions.
