This morning, I woke up to change and feed Sophia. As soon as my eyes opened, I noticed one of my fingers was itchy and another spot between two other fingers was also. I figured it was just dry skin from extra hand washing before handling baby and after diaper changes. I put some lotion on then changed her diaper. I noticed the itching started getting worse and spreading slightly. I put her on my boob to eat and within 30 seconds both of my hands were itchy beyond belief. I was trying to ignore it so I can finish feeding her and then I was going to go see if we had anything in the medicine cabinet (we don't tend to take OTC meds that often so they usually expire before we can finish them). It got worse and worse as little one was truly dawdling through her meal (of course). Luckily I left the monitor on so I called to my husband to grab a pumped bottle from the fridge to finish feeding her and I promptly found some hydrocortizone cream but no allergy meds. By that point my feet started to itch. I slathered on the cream then looked up what OTC meds are safer to take while breastfeeding. It was over an hour until the local CVS opened (one of the longest hours in my life). He went out and got me some regular clariten (class B med). By the time he got home my hands has swelled a bit, too. Luckily, the clariten seems to have done the trick and I will call my OB to leave a message later (I don't see him for another two weeks).
Re: (XP May2012) FYI another thing new mothers need to be aware of
Same thing here except it was mostly just my feet and 1 week postpartum- I think, knock on wood, though that it has cleared up with some antihistamines this week.
