My youngest boys are 5 & 3. My brother and I are also two years apart. Today I texted my Mom and said thanks for allowing us to survive all those years.
I have 3 children who are now adults, two have children. They all tell me often that they're grateful to me for everything I did for them and continue to do for them. That is the best feeling in the world. Your mom will appreciate hearing that so much more than you know!!
