Oo normal lang yan, lola! At 6 months, ang babies ay nagsisimulang mag-explore ng kanilang mga kamay at fingers, kaya madalas silang mag-cross or mag-twist ng fingers without realizing it, parte lang ng development nila. A few of us moms noticed our babies doing this around that age, and our pediatrician said it's just them discovering what their hands can do, nothing to worry about unless may pain or swelling siya or kung laging ganyan ang position niya.
