Ahhh ni memang tricky, especially bila anak dah kenal direct feeding then tiba-tiba kena botol je! A few of us went through this, few mums I know try sikit-sikit introduce balik, bukan force, sometimes warm the bottle a bit or try different teats biar flow dia similar dengan direct breastfeeding. Some babies also reject botol sebab trigger trauma dari jatuh, so go slow lang, maybe let pengasuh try dulu in a calm moment, jangan time lapar sangat. Since dia 9 bulan dah boleh jugak slowly increase solid foods yang protein-rich, tapi I'd check with your paediatrician just to make sure everything okay emotionally and developmentally after the fall, just to rule out anything else going on. Hang in there, mama, this phase will pass!
