Help!!

Ashley

Good morning!! I’m in need of some serious help here. My little one is 12 weeks old today and she’s My fourth baby but she’s proven to be my most difficult. All my other kids were never fussy and never cried, they were always all very content babies. Shelby on the other hand is never content. She’s always crying unless I’m holding her. At this point I don’t know what to do I can never put her down I can’t get anything done. She was sleeping from about 830 until 2 AM and now she’s getting up at midnight and at two And I can’t get her to go back to sleep. We’ve tried everything swaddling, she now sleeps in one of those little sacks that she can move her arms in but all she does is squirm, she’s so restless I don’t know what to do. Any advice would be really helpful. We have a good bedtime routine with a bath and I rock her to sleep as I give her a bottle. Thank you in advance for any help.
