I am 11 weeks pregnant with my first and am a strong believer in breastfeeding. I'm planning to breastfeed my baby for at least 2 years, but will probably BLW. My husband happened to tell my MIL how important I think breastfeeding is. She told him that when he was 2(or 3?) months old they flew from South Carolina to France (they moved there for a year for FIL's job) and she said the stress of the long plane ride "caused her milk to dry up" and she had to switch to Formula right away. She said I need to be very careful not to stress out or this would happen to me. Is that something that is common? Rare? Total bologna? I'm assuming stress would cause some challenges, but this sounds a little out there... But I don't know.
