I’ve got three under 2 I was 3 months postpartum when I fell pregnant I’ve never had c section before but I did this time due to twins sharing placenta They said as my first one I should recover quicker
I also had 3 under 2, 16 month gap between my first and twins. Twin pregnancy was absolutely fine, no complications at all, had to have a section only because they were breech.
Doctors recommend 12-18 months usually but there are a lot of people here with less and even after c-section (including me). There are more risks but I think the risks are still low. It's hard being pregnant with small baby but other than that everything is smooth for me and my doctor is happy with how things are going. So far, I haven't had explicit judgment - very interesting since everything else in my motherhood journey has been judged. I've noticed less excitement and more worry. That was generally our feeling at first too but now we ready for people to get excited with us.
