gigit bawa bibir

Totally normal lah, especially at that age! Babies around 5 months start exploring their mouth and hands sebab developing fine motor skills and oral sensory awareness, it's part of their learning process, bukan ada masalah apa-apa. A few of my mum friends told me their babies did the same thing, and one even said it's sometimes a sign early teething is starting (though bukan semestinya lah, boleh jadi dia tengah discover je mulut dia boleh buat apa). Just make sure bibir dia tak luka or bleeding, and kalau teething symptoms nampak obvious nanti (like drooling lebih banyak, gusi bengkak), you can give him a clean teething ring to nibble on instead, helps a lot! Don't worry, this phase will pass
