Night feedings, overweight baby

Nanay

Need advise, I went for 7 month check up today and nurse told me that my girl is overweight and that I need to cut her night feedings. She is 69cm and weigh 9.5 kg. I usually nurse her to sleep and was told to teach her to self soothe and cut night feedings as she does not need additional calories. She also suggested little cows milk for breakfast to be mixed with weetabix or adult oatmeal, because baby porridge tend to be sweeter. Any thoughts?
