I just wanted to add my experience as a former baby room supervisor. We had severval babies who were far more demanding than the rest and a couple who were extremely challenging but I want to reassure you that they were NEVER left to cry it out on their own or given any kind of lable.
The baby room was very small, which I think is very key, we only had 5 babies at any one time with 2 members of staff. This meant we were able to meet the individual needs of each baby, be it carrying them around, sitting with them, rocking and walking them around, anything to help them settle.
Any good childcare worker, be it nursery nurse, childminder or nanny would not let your baby just scream and scream. I always worked really closely with the parents and I was always honest about how things were progressing.
I hope your baby becomes easier for you as she grows, please consider what others ahve said about silent reflux, it must be worth investigating, if only to rule it out.
Try not to panic about childcare yet, you really do have plenty of time but if it helps you to calm your mind, maybe have arrange to have a look at the different childcare options in your area.
Hope this helps a bit.
