How soon are you going back to work? My dear daughter refused the bottle and i've never been able to make her drink from it since she was able to latch on properly. It's gonna be a tough fight to make her drink from bottle. That said, i did ask the lactation consultant last time about this issue. She said that try to ease baby back to the bottle again by slowly introducing the bottle: maybe feed once or twice a day for the first day then keep trying till she's better then intro more bottle feeds. She also mentioned that after injection's not a good time to force baby to take the bottle if she doesn't want coz she's already traumatised by the injection so better to hold off the bottle for a few days.
I'm a stay at home mum so it's ok that she doesn't want the bottle. I know it's heartbreaking to hear baby cry and refuse the bottle but since you're gg back to work you have to persevere and harden your heart. Jia you!!!
