I've been exclusively BF my 14 week old DD. I used to express 1 feed a day, but she started sleeping 12 through the night from 9 weeks, and so I didn't bother to express anymore as she was only feeding 5 times a day. Around this time her weight gain slowed right down, obviously due to a sudden drop in her feeds, so I began to give her a dream feed at around 11pm. I have the grandparents coming over on Friday to do some babysitting on Friday, and I'm toying with the idea of leaving Formula for them to do the late feed, as I've really got out of the habit of expressing. It's only one feed and I would consider doing it maybe a couple more times in the next few months. It can't be that bad can it? For some reason I feel guilty even considering letting Formula pass her lips before 6 months...
