Brenda,
I understand what you are going through my lil' one is doing it now. Come to find out her molars are coming in. Just take a deep breath and count to 10 many of times. If you have a partner or if her daddy is there with you ask them to help you during the night. If not honey hold tight and it will be over soon. Have you had her ears checked out? Maybe an ear infection?? That is when my children always had the really loud cries, the painful cries (just because this is the only way to let you know that they are hurting somewhere)
Being a mom takes a lot out of a person. I would always call my mom (even at 2 am) asking what am I doing wrong why won't the baby calm down. She always gave good advise. She would say Turn the Dryer on and walk and sway with the baby. (after giving her some teething gel) and sing to her. And ALWAYS REMEMBER baby feels when mommy is upset and not relaxed. This makes the baby more upset. Ya know, even after having 3 kids I still call my mom for the little ideas that she did with me and my brother. It works.
Just remember to count to 10 and home appliances can be the solution to the "big" things that we don't know how to fix.
Good Luck :o)
