hi i am a first time mum with a 9 week old beautiful boy. he has been exclusively breastfed and i am trying to get him to take a bottle of expressed milk so my partner can feed whilst i go swimming etc. baby sidney has a 25% tongue tie which will be snipped next week.when i give him the bottle he just vigorously pushes the teat to one side, hungry or not, morning or night, calm or upset.tried tommee tippee and avent silicone teats so far. about to try others but am unsure if tongue tie will make the difference. anyone had similar problem?any advice greatly appreciated.
