Oh how stressful for you! It will suck if he has to miss it. A doula is a great idea.

I think that most hospitals only restrict video for c-sections - i.e. where there is surgery and if something goes wrong the patient could use the video as evidence in a civil law suit. Check with your ob and/or hospital what their policy is but you should be ok as long as your not planning a c-sect.

I don't think a three week lapse between the birth and meeting your DF will necessarily affect bonding. Some people take longer to bond who are there right from the start and others don't. Everyone is different - as long as your DF gets as involved as possible in the babies care as soon as he is back everything should be fine! Especially if he has 'witnessed' the birth via video.
