Ay, madalas yan lalo na kapag pregnant or nagpapasuso! A few of us moms experience that numbness, usually from the position we're holding baby or from carpal tunnel na common talaga sa atin. I'd suggest checking with your OB or doctor lang kasi kailangan ma-rule out kung normal lang siya or may underlying issue, better safe than sorry, especially pag affecting your daily tasks na with the kids. In the meantime, try changing positions when holding baby, do some gentle hand stretches, at mag-rest ka rin ng mga kamay mo kung kaya, sometimes it's just from overuse or poor positioning throughout the day.
