3 week old falling asleep on Dr Brown's size 1 after taking 2oz. Was taking 5 oz on TT bottles but suffered from really bad wind. is more settled on Dr Brown's but concerned not taking as much and is sleeping less. still got problems with wind as she writhes round and grunts when laid on her back and farts loudly often waking herself up. been using infacol for last 2 weeks. mummy getting no sleep due to her being so noisy even for the brief hour she is sleeping. any advice/ similar experience welcome.
