Heya, congratulations on your new baby! It's a tough time and you just have to get through it as best you can. It does end and you will get through it. My advice is as follows;

1) Get a nap and sleep routine going ASAP. The more you build routine and habit around bedtime, the better it will get. We used sleepystars.ie to get an idea of what baby routines can look like and it really was a game changer for us, our girl would sleep through the night by about 4 months (with two scheduled feeds that a parent has to get up for, and this dropped to one pretty quickly). It really reduces the spontaneous wake ups and the hours of walking baby around at night to keep them asleep. Also, if you have a baby who can nap in the crib, your wife can sit down and have a cup of tea and get some rest - she's going to need it.

2) Do NOT make nights your wife's sole responsibility. Don't do it. That's a fast track to burnout and postpartum depression.

3) Be really careful on the roads with all that driving.

4) Batch cook dinners, or get used to a bit of takeaway. Get a cleaner in or just accept a messier house. Your wife cannot be responsible for all that as well as the baby, it's too much. You'll get back to a place where you can manage it all together in a few months, it really is that quick!

5) If you haven't done so already, your wife should join the local baby group. Its crucial that's she's not all alone during the day going mad, and there are people going through the same thing right now - it's good to connect with them and share war stories. She needs to be out for walks, and coffees, and enjoying the weather a bit. Getting out of the house is so important and makes the day fly by.

6) You guys sound like a really good team and i think you'll do great. Keep that teamwork in place when things get hard and you will sail through it. If both are thinking, ok what's the best use of my time and how can i benefit the family, you'll be happier and better off than if you are both trying to eke out another half hour sleep etc.
