First of all you are a great mom!!!
White noise as loud as a shower helps, pacifier and rocking the baby in small quick motions can help. Look up Taking Cara Babies!
Sounds help my little one! Either the sound of the faucet running (her favorite) or the jhene baby album on Imusic “sleep soul” the “cozy lullaby for nb” put my baby out in 10secs play that and pat they’re back really fast !!
Maybe try a bath then skin to skin? I'm a second time mom and I still get to the point where I feel like I'm going to snap. When you feel like that just set the baby somewhere safe and walk away for a minute or two to regain your composure. Baby will be fine to cry for a minute while you decompress. You got this mama 💕
You're doing great mama! It's so hard when they cry for prolonged periods of time and you've exhausted every trick in the book. Being frustrated or overstimulated is ok and a perfectly normal response. You are not in any way a bad mom for feeling this way. When this happens definitely don't be afraid to set her down somewhere safe and walk away for a few minutes. Maybe some noise canceling ear covers for moments like these could help? Nothing that would block the crying out completely, but just muffle it a bit so your cortisol levels don't spike as high? My little one has been very responsive to baths with me. I bought a water friendly baby sling and we sit in the tub together. I gently pour water over her until she settles and falls asleep. I've seen other moms use this sling in the shower too.
