I see 2 sides to this.

1. Not everyone is net addicted like *some* of us are (lol) and do not look into info etc before TTC, and therefore, probably assume the Obs or Midwives would give some kind of info on caring for yourself and baby upon first contact....but

2. Some things are just common sense as far as smoking, drinking etc etc.

Soooo....reponsibility is ultimately the Mothers IMO, but the Care providers have some duty of care to ensure the mother is informed.
