Last night - worst night since she's been born!

My girl just turned 4 months and had me up all night long. She has always been an amazing sleeper and last night was so NOT like her. Crying and whining and being fussy all throughout her normal bedtime, she REFUSED to sleep in her bassinet - the minute I picked her up she would sleep on me and the minute I put her down she would wake up and cry so I literally had to hold her in my bed all night so she could sleep. She also wanted to nurse all night so I just had my boobs out for her to latch on and off. I know this is leap 4 but I have a real problem with her sleeping in my bed as I know that it's dangerous. And she's sucking me dry! How are you mama's handling this?? I feel like a zombie cow 😭
