Second Baby

🐷
Hello everyone! I'm new to this app but am pregnant with my second baby. My daughter is currently 13 months old and I am 17 weeks 3 days pregnant. I'm just wondering if anyone has any advice on how to keep my one year old from kicking and hitting my belly (and how much of that I really shouldn't worry about since they are protected in there to an extent). I have been so nervous every time she does it. I also am curious how moms with multiple babies got enough rest during pregnancy when fatigue is overwhelming at times. I feel like I haven't slept in weeks since she is teething, my unborn baby is already dancing all night long, and I have to wake up to pee every hour or so lol. Any advice is welcome and congratulations to everyone expecting their very own little miracle!! :) 
Ps. I know it's a little early but I want to be prepared; how can I make my daughter feel included and loved the same as always after the new baby is here? I want her to know that her daddy and I will always love her just as much as we always have.
