Going from one to two

Hi, so I’m 32 weeks pregnant with my second and I’m starting to get anxious about having 2 under 2… I’m also starting to get anxious about my first born and how he’s going to react… he’s 20 months right now he’ll be 21 months almost 22 when his little sister will be born.. I think I’m mostly looking for advice.. other mamas that went through this? How did it go? What did you do so that your toddler didn’t feel left out..

Ps I’m having a c-section so I won’t be able to pick him up and he’s a mamas boy...
