Wa'alaikum assalam, congrats on the pregnancy! Honestly, menyusu while pregnant is okay, baby in the womb won't kena effect, tapi perut mungkin jadi sakit sikit when baby suckles (some mums say it triggers contractions, especially bila dah further along). A few of us tried weaning gradually around this time, macam limit feeding to bedtime only or offer milk/snacks instead, it takes patience but easier than cold turkey, especially dekat toddler. Best you check with your doctor or midwife first, sebab setiap mom and baby different, and they can advise based on your situation.
