T.F.
Congratulations on your upcoming baby to be!
You have time NOW to start transitioning for the new normal. You should have started that transition long ago.
You have a toddler, not a baby. A toddler needs to learn independence, sleep in own bed and room, does not need to be "bf'ing"at night.
I realize you "like it that way" but your life is about to change and the way you like it now will change like it or not. Your toddler is in for some drastic changes and adjustments need to start taking place now. I am NOT bashing you for your choice but keep in mind that you are limiting your toddler by co sleeping, night feeding, and not allowing that toddler to grow to be an independent little person. You don't need a newborn and a toddler that is still treated like a newborn. Empower the toddler. Socialize the toddler. Help the toddler grow up.
I don't know hospital protocol but I would think they would not be allowing you to be sleeping with and bf'ing a toddler right after you give birth to a new baby. Your focus at the hospital should be safe delivery and bonding with new baby. How are you going to feed your newborn and a toddler? The newborn is the one that needs the breast right now, toddler needs a sippy cup.
Start adjusting your routines now or you'll be in for some nightmareish behaviors, acting out and more.
Having another baby in the hospital is not leaving people out. It is a little scary that your concern is so much for toddler that you are not thinking about the newborn and needs for him/her
