Uy, iba-iba talaga ang babies kaya kung nakikita mo na may something unusual sa katawan niya kapag umiiyak, parang stiffness o strain, it's best to check with your pediatrician kaagad, okay? Hindi ako doctor kaya hindi ako makakapagsabi ng sure, pero mas mabuti na i-clarify with an expert. A few of us mums had newborn concerns din before and palagi naming na-ease ang worry once na kinonsulta na namin yung pedia, mas peaceful sleep after, hehe! Kaya go ahead and set up that appointment, mama. Your baby needs that check-up, and you deserve peace of mind.
