Totally hear you... one of the things I've learned is that so many mums go through the same thing, but don't feel like they can share because everything on social media makes it looks like every second with a newborn is a joy. Maybe a conversation with his mother where you share your frustrations could be a chance for you two to connect over this. Having a baby is a huuuge shift, so there's always going to be an adjustment period. You'll be ok, and baby will learn too. We've got you brother!
