Ahhh I feel you, quite a few of us actually faced this juggling act! Honestly it's not dangerous for baby lah, tapi memang physically draining for you sebab pregnant body needs so much energy, so the real question is more about managing your own health and comfort during pregnancy. A mum friend of mine continued BF sampai third trimester but decided to wean slowly around 7 months preggers because she was exhausted and nipples were very sore; another one just let baby self-wean naturally sebab dah kurang interest. Kalau nak stop, best way is gradually reduce sessions over a few weeks rather than cold turkey, less engorged breasts that way. But definitely check with your gynae or doctor about your specific situation, especially if you're concerned about anything, they know your pregnancy best and can advise if weaning makes sense for your body and recovery plans.
