Oo, kayang-kaya mag-BF habang buntis! A few of us moms did that, and honestly it's normal lang, marami pang nagpapatuloy until delivery, as long as kaya ng katawan mo. The thing is, bawat mama is different, kaya kung may concerns ka about contractions or anything physical, best to check with your OB para ma-monitor lang, especially kung high-risk pregnancy mo. Your eldest doesn't have to stop if you're not ready, some kids naturally wean on their own eventually, at walang pressure na.
