Hi op another person saying it's normal to have a screamy baby when you get home from hospital. Don't know why no one tells you this, it's totally normal it seems. It makes you feel like a failure. Which is shit. Considering you have just given birth and are exhausted and stressed out.
Some Breastfeeding info-
You have enough milk.
You are producing colostrum at the moment. Highly calorific and priming the gut. Baby by constantly latching on is priming your body to make breast milk. This is normal.
When your milk 'comes in' you will notice. Your boobs will get bigger, may leak and you may feel 'let down'. This is literally the milk being made and flowing through the milk ducts. Can be quite tingly.
You have enough milk.
Screamyness-
From the baby's point of view they were warm, totally supported in water, it was dark, whooshy noises from your body.
Then they were squeezed out into a new world that is comparatively cold, bright, air rushing through their lungs, it feels odd not being in water, strange noises. It must be terrifying.
Solution- cuddles.
When they are latching on they are getting comfort from the warmth of your body, you are supporting their body and they are getting food.
You can replicate this by doing extreme cuddling aka biological nurturing.
Take off baby's baby gro, take off your top half clothes. Put baby upright on your chest in a nappy. Put a soft blanket over both of you and lie back. That bit is key. Get oh to make a pillow nest on your bed, so you can lie back doing this cuddling. If she falls asleep make sure you are all propped up so she can't roll off, in case you fall asleep too. Which is totally natural.
Your oh can do this too, so you can get some sleep, if you don't want to fall asleep cuddling her, and take turns sleeping.
I hadn't heard of this, so what we did was DH do a bouncy walk around with blink 182 on the iPhone playing, bizarrely the only thing that settled her. I feel sad I didn't know about extreme cuddling, I'm sure she would have liked that.
Bf shouldn't hurt. If it does the latch isn't right. There are reasons for it not being right, but you need someone to see what you are doing, to check it. (It can be tingly/ stingy for up to 20 secs at the start, but not excruciating)
I advise you to call the Nct bf helpline when you can, and they will do a telephone consultation. And hopefully tell you how to get an in-person consultation.
It's worth getting the latch checked again. Ime Heath professionals don't always know bf facts. Even in hospital. Its just too easy to give formula, when that is a quick fix, but doesn't get to the root of the issue.
Hope that info helps, you are doing great, congratulations on your new baby! Hugs
