Supply drop and trying to help with a little supplementing formula.

Ch

So I had an extreme supply drop!! 4 months EBF ( with maybe a handful of bottles of breast milk in between when she was still hungry). I’ve even been taking herbal medicines for lactation, even bought a wireless breast pump to try and help and still nothing. My daughter just turned 4 months and constantly wants to be at the boob eating and gets mad when she empty’s both of them. She won’t take a bottle of formula! I’ve tried so many different types and temperatures and nothing. She has no problem taking breast milk from a bottle but everything I’ve stored she’s ate!! She got her first tooth at 19 weeks so just recently started her on baby food for breakfast, lunch, and dinner as well with breastfeeding. And still she is hungry and hour later. She sleeps maybe and hour if 2 tops at night and wakes up to eat. Like clock work! I’m just trying to give her a little supplement of formula to help fill her tummy when she empty’s both boobs and still fights cause she’s hungry and can’t get anything out but she won’t take it. Any suggestions on what type to try or what I could possibly do to try and help. Thank you in advance!!!
