My first struggled with bowels on cow and gate milk for about a month - was really uncomfortable trying to poo so I changed to Kendamil and he was a different baby so you could always try a different brand of milk and see if that helps?? If she doesn’t get on well with it could always change it back. Go with what you think is best for your baby. Their digestive system does change at this age aswell! Xx
You can also try either mixing ready to feed pre made formula with powdered bottles or alternating
Also we have been sitting our little one on a potty for quite a while now from 6 months I think The gravity seems to help
We had a similar situation with our baby so we’ve used co lactase drops in his milk and he was a different baby within a couple of days. Sometimes they struggle to break down the lactose in the milk, especially for the first 6 months. Might be worth a try so you don’t necessarily need to change her formula
Our girl has had issues on and off Health visitor told us to make bottles to ml rather than oz as water content is higher. Some old school also suggested cooled boiled water no more than 3oz a day to help soften. We also had to use laxative on and off. Also pureed prune she had quite early seemed to help. Not sure if that's helpful Hope baby feels better soon
