Ay oo, may mga available pa rin talaga, pero honestly hindi na ganon karami ang choices ngayon compared dati, most ng mga makikita mo ay may holes na talaga or designed for flow already. A few of us tried sourcing those solid/practice nipples from online shops like Shopee and Lazada, pero mostly from international brands like MAM or Philips Avent ang luck namin, kaya medyo mahal and shipping time. Better approach siguro ay mag-check ka ng local baby stores or tanungin mo ang pediatrician mo kung saan exactly makakakita ng ganitong type locally, baka mas mura at faster delivery!
