Hayy, normal lang yan sa 8 months, maraming babies pa lang talaga ang hindi interested sa solids at mas prefer ang breastmilk, kaya don't worry too much! A few of my mum friends had the same experience, at ang common culprit ay hindi lang teeth, sometimes it's just preference, or the texture of what we're offering, or kahit excited lang sila sa milk pa rin. Try exploring different textures and tastes na soft talaga (like mashed avocado, egg yolk, rice porridge with fish), at go slow lang, walang pressure, ang breast milk niya ay sustaining her well anyway at 8 months pa lang. But since you're thinking it might be teething-related or if she seems to have trouble swallowing or shows other signs na off, best check with her pedia para ma-rule out any concern, okay?
