Baby won’t feed help!

hanna

My 10 week old baby hasn’t been feeding properly for the last 3 weeks I’ve noticed she’s been getting worse every day to the point where she’s only been drinking 60-90ml every 5-7 hours last night I took her to the out of hours GP they said she’s looking healthy. this morning I had a Health Visitor over and she weighed her and said she hasn’t lost weight to the point where it’s concerning. I don’t wanna sit around and wait for my baby to get worse because these ‘professionals’ keep telling me she looks ‘fine’ I really need mums advice and what techniques I could use.

I forgot to mention she’s bottled fed.
