Wah, mommies yang kuat ni! Honestly, weaning at 3 tahun is totally okay, a few of us did it around that age by just being consistent dengan "milk time" je, not on-demand throughout the day, then gradually reduce. For the 1 year 4 months, boleh tunggu slightly longer since pregnancy hormones might make bf uncomfortable anyway, so sometimes baby akan naturally interested sikit less. One of my friends yang pregnant while tandem nursing, dia cakap yang most important is take care of yourself first, paip payudara boleh jadi very tender, so maybe see your doctor about whether it's safe for you to continue and ask about proper weaning timeline, especially since you're managing two at different stages plus pregnant. Hang in there, mama!
