Everything is going to be fine I felt the same way with my first. Being sick is not fun but its worth it when you see your baby's face. Hang in there I hope you have a fast 20 weeks
I had my first at 21 it's normal to be scared I was but when you see you Lil one crying your going to hold him or her close to you and sooth them and help them you won't worry snit yourself you'll be fine......always pray about it
I'm 21 weeks too.. I still have morning sickness and bad migranes.. Youre not alone, it will eventually be over.. Don't worry about not knowing what to do if baby won't stop crying, you'll know and even if baby doesn't stop crying you can cry too, it's what I did with my first when I was 22.. Everyone will make it out okay.. I promise..
Your motherly instincts will kick in, so don't worry too much about it. I am 17 wks ftm also. But i have been babysitting babies since I was 8. So it will just come natural to you. I am sure you will be the best mother you can be.
I know how you feel I'm 21 yrs old 15+6 with baby number 2. I had my first when I was 15. I'm constantly sick morning/afternoon/and night I know it's no fun. But when it comes to the baby crying you'll know what they need. Between being hungry, needing a diaper change, gassy, tired, or just wanting to be held. You'll be a mother you'll know a lot more then you think. Plus the hospital usually makes sure you know how to do almost every thing before you leave. Good luck and congrats you do fine :)
