I did this with mine and she wanted nothign to do with him. Acutally during both pregnancies. A week after the kits were removed( after 8 weeks) she was begging for him to come back. Each chin is different. Test the waters with him and the kits, then with him and her, then the group. I did this in the tub for dust bath time, it gave me an impression of how it was gonna go. Mine didnt go so well. Hope yours is better.
