Eh ada je! A few of us have babies close together like that, it's definitely challenging tapi doable lah, especially since your first one dah 1 tahun 6 bulan, so dah a bit more independent compared to newborn stage. The tiredness part is real, so make sure you get help from partner or family members, and don't hesitate to ask your mum friends or family to help with the older one while you rest during pregnancy, especially first trimester.
