How close?

Hi guys- don't know if this is the right group but anyway 🤷🏼‍♀️ I'm 22 though..

I currently have a 6 month old, and wondering what people think about TTC again now. So she would be about a year and 3 months ish **assuming** I would conceive this month (we have very high fertility in the fam)

What do some mums on here think about the age gap? Would it be ridiculously hard? I know 2 under 2 is hard but I'm not sure it would make much difference if I waited maybe until December/Jan ? Thoughts pls 🙃
