When to try for #2

My baby is 14 months and breastfeeds. He’s never really slept through the night and sometimes the sleep deprivation is awful. It seems to be improving for now. I really really want another but I am so conflicted on when to try. It took us 3 months to conceive him - I was in my later 20s and so was my husband. I’ll be 31 next month and haven’t experienced any losses and I’m very physically healthy. I’m so scared of waiting too long and having difficulties getting pregnant but I’m also afraid I’m not ready for another. Help! How did y’all decide? Is it harder the second time around? Thank you all 🤍🤍🤍🤍
