My EBF 17 week old was born on the 9th percentile but soon found her curve on the 3rd. TMI but I went to get her weighed as my AF arrived despite exclusively breastfeeding. She has dropped to the 0.4th and weighs 10lb5 at 17 weeks. Initially we were doing formula top ups as breastfeeding was a real challenge, but for some time we having done that for some time. She is otherwise happy, albeit doesn't nap well so is a bit grumpy sometimes! Should I be concerned/consider formula top ups again? She is lactose intolerant so would need to be dairy free milk prescribed by GP. Anxious mama here!
