I know what it’s like to go through this. My wife and I found out early on that we couldn’t have children naturally. Thankfully, Hashem sent us his messengers from Bonei Olam, who helped us tremendously. After about 4 years of running to doctors, we finally had twins!
Going through fertility treatments is very tough. Most people can’t understand what it’s like. My wife and I are happy now that we have 2 children. Would we want more? I don’t know. I choose to look on the bright side. We have a son and a daughter, so we fulfilled pru ur’vu according to all shitos. We won’t have to worry about the financial issues that sometimes come up when you have 6 or 7 kids. We don’t have to worry about getting burned out from raising kids all the time.
If, one day, we decide to try again, we’ll go back to a doctor. For now, we thank Hashem for sending us what we have. I’ve always been told that Hashem only sends us what we can handle. Maybe I wouldn’t be able to handle the stress of more kids? Hashem knows what’s best for me, so I leave it in his hands.
