can an 11 month have purely cows milk?

[esmebaby]

my dd is nearly 11months, she was breast fed until weaning when we switched to formula as she preferred food and i was starting to dry up (sorry for the crude term!) anyway shes never really taken to formula and even now only has about 16-18 oz a day,which has to be really cold out of fridge, she wont touch it if its even a touch warm! 6 oz is cows milk which she has for breakfast. she wolfs the cows milk down but is really fussy over the formula. can i put her on cows milk exclusively yet?
she only weighs 18lbs but health visitors say shes fine just dainty, has anyone else but their child exclusively on cows milk before 12 months?

guidelines are cows milk as a drink only from 11 months. i however, didn't want dd to have formula so moved to cow's milk from breastmilk at around 10 months. for the sake of 1 month i would go with cow's milk. does she have a good diet? eats plenty for her vitamins etc?

sorry- guideline is 12 months of course!

I'm sure dd was!!! She kept nicking DS' milk roiund about that age anyway and she is yapping away beside me right now - it certainly hasn't doen her any harm.

thanks ladies! yeah she eats a healthy diet better than me ha! ill put start movingher on to cows milk through rest of the day x
