My husband left to get food so he could get out his nervous energy. The snacks were for me. They may tell her not to eat, but honestly her body will tell her when she no longer wants to have food. As long as she us up to eating she should! I ate on day 1 but day 2 I could not longer stomach it.Yikes. Hopefully it doesn't take that long but I'll take it into consideration. Did you get food delivered at some point? Don't think I could eat only snacks for that long.Best of luck for a safe delivery! Bring lots of snacks because inductions can take a bit sometimes. It was 36 hours for me from arriving to the hospital to delivery.
The induction time depends on how far along your wife is. The process can take 3-5 days for some people! I read a book for most of day 1, bring entertainment in case she needs a bit more help to get going into labor.
