My son just turned two in October. I only talk to him about it and the baby when his dad's not home since he's still weirded out that were having another one. He thought ttc would take longer than a month. He was planning on 4-6 months. But Henry's still not getting it lol. He just wants to headbutt my stomach! I don't let him of course and it's light. But he gets very excited about babies on TV and baby dolls when we're at my sister's and her niece has them out lol
