Oh how I need some help! My girls were doing so well sleeping at night just last week. They would take two-three naps during the day and would even stay awake long enough for "play time" after their bottles. Now, all of the sudden starting Sunday night after their last bottle (usually about 8-9 pm) they will not sleep! In fact, they scream and cry. I go in and take turns holding them or trying to console them but this will go on for hours. Until their next bottle. After their next bottle, which is 4 hours later, they go straight to sleep no problem and sleep for 5-7 hours. What the heck happened? Oh and I should add that they are super sleepy during the day now, no play time and I can barely keep them awake to feed them. They aren't finishing their bottles even. I'm losing my mind! I thought we were doing so good! Any suggestions? Help!!
