I have termed because of failure to transition. I had a little boy from 6.5 months til 9
Months, 3 days per week. The poor kid cried and screamed bloody murder all day every day no matter what I tried -feeding, diaper changes, naps, walks, toys, change of scenery, holding. Didn't matter. He was like that for everyone but dad. I tried my best, but couldn't deal with it in the end. Hard to do but made life better.
