My DS is ebf and has been BLW since 6mo old. He's approaching 8 months and I took to him weighed and he'd only put 3oz in 6 weeks. My hv was not bothered said he's thriving and normal as more active (he can sit, roll, spin, crawl backwards and rock on his knees)and filling up on food not so calorific as milk. He was almost on 91st centile before so not (ahem) tiny ! Do I need to be worried? My smug anti BLW MIL is having a field day :( I'd been laid back till this point with the milk till 1 mantra
