My 12 month old was exclusively breast-fed for just over 8 months. I then spent about 6 weeks very gradually phasing out bf until we got down to one morning feed a day which she is still having. I have replaced the breast feeds with Aptamil 'first' and have never used their hungrier baby milk or follow-on milk. Have I made a mistake here? I realise I can now introduce cow's milk but have a box of Aptamil to finish first. Should I introduce the follow-on milk for a month or two before starting on the cow's milk? What about the growing-up milk which I have only just noticed exists? Is that preferable to cow's milk? Obviously I want to give my dd the best option available.
