Weaning and milk

Noleen • Married summer 2015
My little girl will be 5 months tomorrow and I have been giving her Ella's kitchen foods at lunchtime for about 2 weeks now (health visitor said it was fine). The foods are for 4 months. Anyhow, she was still taking her 5 bottle feeds as well as this but she has started taking a little more of the food and slept through the night without her fifth bottle feed. I'm wondering will she do the same tonight. When do you drop one of their bottle feeds? I'm always worried she's maybe not getting enough to eat
