my ds is one in two weeks. ive run out of formula so for the last 2 mornings and evenings hes had cows milk. i thought it woudl be ok giving it to him a bit early as his diet is so good and i make sure he eats very well with a really good balance of all the different food groups. now ifeel a bit guilty though that i may be doing him some harm and think id better get some formula tomorrow at the shops.... what does everyone else think? i breastfed exclusively for the first 6 months to give him the best start so i dont want to do anything now that may hurt him or affect him later on. hes also had upset tummy today (bad nappy) and i didnt know whether this might be anything to do with it?
