love my niece and nephew

So a few times in the last 2 weeks, my niece and nephew have made some comments about Mark and I not having children. My niece (4 yrs old) asked me about it and I said something along the lines as God has decided it is not what He wants for us. She said maybe it would change someday and if so, I would have to stop working so much. I laughed and said we would just take the baby to her house for her mom to watch it...and she did not find that funny. I told her instead I have her and her brother and sister to love and spoil. She just smiled. Then made a comment about her maybe coming to live with me when she gets older. The yesterday my nephew and her were talking about it. Honestly it does not bother me. I do like to hear what they think in their little heads about it and likely have heard it from adults around them. I just like listening to the innocence of it. I know my mom tried to protect me with Evan but I wanted to hear his insight. They are cute. Maybe it is ok now as it has been almost a year since we stopped. I am still not looking to mothers day...which is 2 weeks away or so. That day will be hard for a while. Praying for strength for us all.
