Hi I'm new to all this and could really use any advice from more experienced mums. My 14 week old daughter really struggles to feed from a bottle.... loads of milk leaks out of her mouth... I measured and she's losing about 3 ozs of milk from every 8 oz feed. I've tried avent bottles and all teat sizes, DR Browns and all teats, Tommee Tippee Healthcheck variflow, Tommee Tippee Closer to nature. Have changed feeding position as well. Am starting to worry now as her weight is dropping has gone from 98th to under 50th centile. My older son was breast and bottle fed with no problems so am pretty sure its nothing I'm doing wrong!! Any tips?
