Ahhh mama, I totally get the panic lah, pregnancies yang rapat macam ni memang overwhelming at first, but honestly many of us went through exactly this and survived (and even thrived!). The good news is your first one is already toddling around, so you know the routine already, and sebab dia still on bottle you actually got more flexibility jugak lah, some mums I know yang dalam situation sama, the older sibling ended up helping with the baby, which is actually sweet. Maybe focus on getting through the first trimester first, take things one day at a time, and lean on whoever boleh help you, partner, family, even a part-time helper if possible lah, because this round memang more demanding with a toddler around. You're stronger than you think, and it'll get easier once the shock wears off!
