Baby's cry, a lot. Well maybe that's just Ariana. Nothing can be wrong but they may continue to cry relentlessly. Unless you have time on your hands, and can always  pick them up then go ahead and pick them up. But if you don't have the time to pick them up all the time, then pleaseeeee let them learn discipline from a young age. Comforts nice and goods but don't let it happen too often e.g. As soon as your baby cries and you know they're fed, changed, warm/cool - whatever the case may be, and in a safe environment where she hasn't fallen/hurt herself, then don't pick her up. Not yet anyway, let them cry it out, it's hard, it's tiring. But if you need them to learn to comfort themselves then this is necessary. We've been doing this to Ariana and sometimes it even lasts 2 hours, but hopefully she learns soon. I only wish I didn't pick her up straight away every time she cried. But hey we learn from our mistakes, and sometimes too much comfort from you when your baby is completely fine is a bad thing. But if it does get too much, leave the room for 5 minutes to calm down but make sure your baby is in a safe environment first! Don't worry 5 minutes won't do any harm as long as they're in a safe environment.
