My Dd is now five weeks old and all is well apart from this very strange pins and needles / cramp sensation I keep getting in my hands and arms. Now she's no light weight at 10ib 10oz but it doesn't just happen after I've been holding her for a length of time, it also happens if I'm holding the phone, a pen or even if I'm just sat still (a rarity I admit !) Any ideas what this could be, it only came on when she was 2 weeks. It's not painful but can mean I can't pick her up when she's crying as it sort of goes into 'dead arm' and I'd be afraid of dropping her!
