Could really use some feedback because I know I’m not the only one

Is there anybody else who is completely confused and conflicted on whether they want to add one more baby to their family? I cannot believe how much I am going back-and-forth on whether I want four children or if I just want to stick to the three I am blessed to have my daughter just turned four years old in April my son turned two years old in January and I just gave birth to my third baby which is a little girl and December now I know I’m barely going on five months postpartum but as you can tell all my kids are close in age I myself will be 37 this year and I don’t know if I want to keep having little ones once I hit 40 if I should just be glad in stop now!
