The general consensus appears to be that you should start with a small dose (0.5 mg) to check tolerance. But, be aware that with such a low dose, she may experience adverse effects without any 'benefits'. There are several websites that offer dosing schedules. Search the forum; you'll find a few that are mentioned. Some are less popular than before. Use it no more than twice a week to avoid receptor desensitization. After the flushing and nausea, she probably won't want to use it much. Oxytocin is another option to look into for the bonding aspects.
Regarding the earlier part of this conversation, the forum's reluctance to assist you was justified. It should serve as a reminder to be mindful of how you frame things. Whenever you mention 'giving' a grey-market substance to someone else, it's going to raise red flags, regardless of whether it's a spouse, parent, or child. I'm not judging, but keep that in mind. You'd have gotten a completely different response if you'd said, 'My wife bought this, and I'm trying to get information on it' or something similar.
