HI Ladies, need some encouragement!

I have two DDs, oldest is 2.5 and the youngest is 10 months. From the time she was born, the younger one is "high needs". Screams in carseat, refused bottle & pacifier, if anyone besides my husband, me, or one nanny watches her she screams. the entire time. Won't let my family hold her, etc. Still doesn't sleep through the night. Sleep training took three months... I dont want to sound like I'm complaning because I'm so lucky she is healthy but sometimes I am overwhelmed by how I have to hold her all the time or I have to deal with non stop screaming, and I also feel sorry for my older daughter.

I just kept thinking she would grow out of some of this. We also made things harder on ourselves by moving 3000 miles away when she was 6 months old. I am so worried she is going to be a super sensitive, anxious person (she must take after me...) and really struggle in life. Do I sound ridiculous? I'm hoping there are some other mamas out there to commisurate and tell me it gets better! Help!
