Weaning?

If baby is following their curve don’t be concerned, if they are dropping curves or not gaining at all speak to your hv or dr. Adding food does not mean baby will gain weight, if they start to drop bottles/ feeds too it may mean they aren’t getting what’s in the bottles they need, or what they need from breast milk

I'd talk to your doctor for advise

I think when baby starts weaning their main source of calories is still milk so I'm not sure it helps with weight gain? I'm not sure though. Definitely speak to health visitor or doctor

No because even when you wean babies they are meant to get their calories from milk. Definitely seek professional guidance.
