Baby always clenching right hand

Is it normal for 2 months+ baby to always clench fist so much? Especially his right hand, always clenching. He can unclench his left hand tho. So when we want to reach out to the hanging toys, he still not able to hold it as his fist is clenched. He doesnt look like in pain or hungry etc. i tried to open his hand cs i stressful see him always clenched 😂 also tried massaging his hand then he will clench back
