Thack, my top tip, is to nap when the baby does, especially in the first few weeks, when you are recovering from the birth etc
I always bathed my babies after our evening meal, they tended to sleep longer and it’s the start of a routine.
I kept the room dimly lit at night rather than all the lights on too. I wasn’t able to breast feed my youngest so one of us would go to bed early, the other one would stay up and try and feed about midnight, whoever did the late shift got up and the night feeder got a lie in. I wasn’t an insomniac then. I loved the night feeds when I had other children too, it was a quiet time, when the rest of the house was sleeping.
In my experience the first couple of weeks were quite easy, but at 2 weeks, it’s like they know they’ve arrived on the planet and make their presence known. Good luck!
