Hi! I have been feeding my baby girl HIPP formula since she was 2 months old and from past 3 days she has just stopped. She doesn't want it anymore. Putting feeder in her mouth in the first place is a huge task and when i finally do it she just pulls it out of her mouth. I am worried that she might start losing weight. Im giving her an apple and a banana daily and some Cerelac. She is eating fine but not drinking formula at all. What do i do? Should i try feeding her a different brand? Lebenswert? or Holle?
