Try biogaia. I usually also massage tummy in circular motion with EO tummy time roll on. It helps. How is her solid food? What type of food did she try? My LO last time couldn't take butternut squash / pumpkin/ beans, he wouldn't poo
maybe you can try bicycle cycle for your lo legs..it works everytime after I have done this exercise for my girl, she will poop (:
Help her by cycling her legs every diaper change . Apply ointment on her tummy . Pls give her some gripe water
Try giving her banana Or those banana oatsmeal. Then massage her tummy.
