Urgent help needed, I started switching my little one to bottlefeeding 1 1/2 weeks ago and I am now doing 4 out of 7 feeds by bottle mixing up 5oz (what the tin says for baby weighing more than 10 1/4 lbs). The problem is the feeds are taking so long. Including winding, it can take nearly 2 hours to get her to take 4 ozs. I switched to the Avent 2 teat, but its not making any difference. Has anyone got any advice before I lose all my hair!!!!
