Rest when you can.
Keep the long game in mind; the crying and needing you incessantly is only for a short while in the grand scheme of things.
No shame in walking around at night with a podcast in your headphones if baby is having a hard time sleeping (I wore a circle around our island with two of ours doing this).
Take care of your spouse. Find someone to come hold the baby for an hour while you guys get a cup of tea or grab a bite to eat alone.
Every baby is different, every day is different. I have friends with little ones who are trying to figure out the equation of a+b=happy and calm baby and itโs just not realistic. Go with the flow, every day will have its unique ups and downs. A little grin will give you enough energy for a week.
Soak the snuggles up! Congrats to you both, and welcome little one ๐
