Aww, I know sleep is hard to come by, lalo na ngayon! But honestly, I'd check with your OB first about any tea or herbal drinks habang breastfeeding, better safe than sorry, diba? A few of us moms here have asked our doctors about sleep stuff, at sabi nila, mas better muna mag-confirm bago mag-try ng kahit ano. Your baby's still so tiny at 10 weeks, so it's good na cautious ka. Hope you get some rest soon, mama, you deserve it!
