Ttc second child...?

I have a 7 month old already and my husband suggested last night about just "seeing how it goes" as it took nearly a year and a half to conceive LO. I was a bit taken back as he isn't usually the one to suggest big life changing events out of the blue like that 😳

I know the doctors tell you you're extremely fertile the first year, but how true is that?

If I did conceive in the next couple of months my LO will be a year and a half ish, is that too soon or just perfect age gap?

I should add I'm 33, so clock is definitely ticking before I feel too old.........

I do want more children(max 3) but I dont want to take my firstborn's baby stage away too quickly? Or is that about the right time?

I had a plan to start ttc no.2 April- May 2020, having had a summer baby it sucked being hot all the time 😆

I dont really have female relatives/friends I can talk to so I'm reaching out to you ladies.

Just looking for feedback and experiences of mamas with close in ages and how difficult it is?

Edit: Had an induced vaginal birth (no tears just a graze) Once contractions started I had LO just over an hour later. Dreading next birth if first one was very quick.

No negative comments please, I'm just looking for advice. Thanks.
