I am 38, my husband is 42. We have a 4 year old son. The last four years have been seriously challenging. My son has some medical issues (not life threatening, but requires lots of time with doctors and a lot of sleep deprivation for his parents). He is also has challenging behavior issues, which we are working on with the help of his pediatrician and most likely some counseling. Your previous posts on the challenges (the reality) of parenting really resonated with me.
Given the challenges that you have outlined in your previous posts..I often wonder why people have more than one kid. The only reason I am even considering another child is to give my child a sibling. What do you think? Should we try for another child?
