Just wanted a bit of advice really. My 5 week old Is doing brilliantly with bf but I would really like to introduce one bottle a day so my husband can do an evening feed. Ideally this would be expressed milk but given i have a 3 year old aswell my time for expressing is limited. I'm nervous about giving formula tho. Don't want to leave it too long as I've heard between 4-6 weeks is best time to introduce one. Think I'm apprehensive incase he prefers it too! Any advice welcome!! Ps my first went exclusively onto formula at 8 weeks happily as was losing weight because I was poorly and couldn't keep up with feeding. Thanks!
