6 week growth spurt

Oh mommas , I'm going NUTS!! This is day 4 of the 6 week growth spurt/sleep regression/fussiness madness and im exhausted!! I've never doubted myself as a mom until this time, baby #3 and I feel helpless trying to soothe and comfort him... Dad is trying but Caleb only wants me and still cries..I know it will pass but in the here and now I'm feeling overwhelmed and fussy myself 🤣 I just wonder how long this will last for...just when we think we get a routine BOOM 🤣
