One and done or one more?

I 36F and my husband 31M have talked a lot about our family planning and I wanted to get opinions on those who have an only child and those with multiples.

When my husband and I first got together I was pretty sure I didn’t want kids… fast forward we ended up pregnant and now have an 8 month old I love. It’s been a challenging process since we have no support and my husband immediately went back to work after I had her, I also really suffered with PPD and PPA.

My dilemma is that my husband would like to have another… I worry about if I could handle two kids, working full time and still having any time for myself… it’s hard enough on maternity leave and with just one.

I do worry that I’ll regret later in life my child not having a sibling.

Any opinions or thoughts on this?
