I breastfed my daughter for 1 year. Some of her best feedings were at night. I, too, would take her to bed with me and let her nurse. No matter what, a newborn is going to need to eat in the middle of the night. From what I have read, feeding your baby formula, or even cereal mixed in with the formula, does not promise anything. If your friend pumped a bottle before bedtime, it would not hurt her supply at all, and it would make it possible for her partner to take a turn feeding the baby sometimes. Also, please remind her that it is a good thing when babies wake to feed. Their tummies are little and need to be filled often, especially during growth spurts. I also read (can't remember where) that babies who wake frequently in the night are less likely to suffer from SIDS.
oh, I almost forgot. Yes, nipple confusion could happen. I waited 6 weeks before introducing breastmilk in a bottle AND a pacifier, since both can cause confusion or preference. My daughter had no trouble and would happily suck on anything, but some babies develop a preference.
