New dad trying to help wife as I start work full time.

Our baby girl was born end of September, I am just finishing up a month of paternity leave and have been helping a lot. Lots of cooking, taking baby overnight with pumped breast milk etc. so that she can get 6-7 hours of sleep at a time.

We have started to move to a schedule where I am sleeping more through the night and I am just worried about the toll on my wife, particularly her sleep. Any strategies that worked well for anyone?

I can definitely take more responsibilities on the weekend but as sole bread winner at a job, I can’t put that in jeopardy too much for our future sake.

Any advice?
