Slow baby weight gain.

She’s 10 months now. And last month I noticed she hadn’t gained any weight at all from at least December 11th probably longer. So I took her to the doctor they said it was fine and to give her more solids but she had been refusing them. Now she is not and she’s good with it them but she didn’t want breast milk and now it has kinda gone. It’s been 7 weeks since her last weight and she eats 3 meals and some snacks but she I’ll only have breast milk once or twice a day. But has only gained 1 pound in 7 weeks I’ve read a healthy weight gain would have been 1.5 at least and she hasn’t reached that. I’m thinking I should give her a could formula bottles a day. Maybe twice and breast feed before bed. I’m just curious what other people would do. Does that sound right?

Edit

The doctors told me they don’t give advice on baby feeding. And I should as a health visitor which is like a low standard nurse that just makes up things as they go. It’s a very bad program tbh lots of people have problems with them. I can’t just ask them her doctor. They said she they don’t want to refer her to a feeding specialist either. I’m not in the US but I basically got a go f yourself and feed her solids but I’m not really sure if it’s enough and maybe she needs more milk with her solids.
