Sounds dramatic but I feel like my forearms could snap lifting up my baby. Specifically along the ulna bone about half way between wrist and elbow. Is this a thing? Should I be doing exercises to strengthen the muscle? Or lifting him differently? He's 10 months and 11kg. His sister is 2.5yo and also 11kg (don't ask how I made one 2nd centile and one 99th centile child 😂) and it feels completely different lifting her, possibly cos her torso is smaller cos her limbs are longer so the weight is spread out a bit more. He's just a wee solid barrel. I've read about "mummy wrist" but that seems to be in a different place.
