Hey girl.. dont worry about your baby.. she's doing fine!!!
My boy is 8mths old now.. and he's only drinking at most 150ml milk per meal.
He feeds every 3 hours somemore! so dont need to worry that your baby is undernourished!
One thing I learnt about feeding solid food, dont rush it and make it fun! if she dont want it, dont give.. try again later.. when babies are hungry, they will eat.
