DD is 11 days old. Started off ebf but due to tongue tie and supply problems we have ended up mixed feeding with me expressing. Went OK at first with a bit of wind and posseting. for about 24 hr now she has been bringing up significant amounts of formula feeds with forceful vomitting.
I'm working on trying to increase my milk supply but only minimal success so far. MIL has suggested changing formula in the mean time. Would this help and if so which should we use? Using aptamil atm.
