Would I be crazy to have two more children?

So, I know this is a super personal question, but I’d like some outside viewpoints.

I am currently 33 years old (husband is 35).

We have 3 kids—ages 10, 6, and 6 (6 year olds are twins). I have been pregnant twice.

We have been TTC for almost a year for baby #4. We had every intention of having 3 or 4 kids total, but after the twins we knew we wanted the 4th. I wish we had really tried a lot sooner. I sort of thought it would just happen, but it’s not.

Every pregnancy has taken me at least two years to conceive.

My question is: I will be grateful to have one more baby, but now they are going to be so spaced apart. My youngest are 6!

Would it be silly to try for a 5th a year or so after we have #4? So they have a sibling close in age, or do you think it won’t matter or that 5 children is way too much?

My kids are already 4 years apart in age and it’s not always easy. The twins are definitely easiest because they play together and go through similar milestones.

Love to hear your thoughts. ☺️
