Cows milk for dd aged 9 months, advice please!!

[gemitygem]

Have been very naughty and run out of formula today. The village shop doesn't sell it and have no transport to go further afield. Gave dd cows milk tonight instead, she gobbled it all down.

Is this terrible, know I should be waiting for 12 months! She still has two feeds during the night which will also have to be cows milk too.

Watching this with interest, as may need to give cow's milk to my DC at this age.

Didn't they put us entirely onto cows milk at 6 months? I think the problem is that it doesn't have all the nutrients that they need.
