age gap 1st born and 2nd born

My first baby is currently 13months old and Im 36 weeks pregnant. So the age gap is really pretty close. To be honest I still have no idea if I can manage both as my first baby is super active and at a very curious stage. But i think the power of a mother will help us go through all kinds of challenges. Hehe

My sister had her first and second at a close gap. She conceive the second when her first was 4 months. Though they are 11 months apart but they are born different years.
