For those not already pregnant again in this group, when are you planning to ttc again if you are having more babies?

I’m undecided if we should ttc in August after his first bday or wait until December to give me time to stop breastfeeding, have my cycles regulate a little and to avoid the chance of another summer baby . I also want to avoid having a due date again in august. It was hotter than hell to be pregnant in the summer last time since where I live people don’t have Ac. And also I don’t want their birthdays to be within 3-4 weeks of each other. Does anyone else have this concern or is it just me? I’m undecided though since I kind of want them to be closer in age and waiting until December means that they will definitely be 2+ years apart. What are your plans?
