I'm on baby #3 and felt like this my whole pregnancy. I'm 3 weeks out from delivering, and I've been talking to my oldest who is also almost 4, that mommy is not feeling good, and will need a bit to collect my thoughts and try to find some energy. He finally got the idea, and every time he asks me to hold him, I'll tell him, when your brother is here, I'll be able to pick you up again. He understands. He is aware that there is a baby in my belly. So much so that he has come to ultrasounds with me and has felt him move. He's excited to say the least, lol.
It’s a totally normal feeling! I don’t have much time to type but you’re not alone!!I promise that!
