Congratulations! In a year from now, this will seem only trivial, and you both will be enjoying your beautiful kid. As a father of two, I have some advice for you:

- things will get better. Slowly, but still. Take it day by day, and accept that times are really, really tough right now. Acceptance is the key here.

- at least consider to stop breast feeding. My wife had similar issues as yours, and the sleep deprivation was killing her. I know there's a big pro-breastfeeding lobby, but there are no convincing and significant scientific studies that say conclusively that breastfeeding is better OR worse for your child. We gave our 2nd formula after a week or two, and we were all happy with it.

- do what feels good, trust your instincts. Don't listen too close to other people's good advice. Including this one.

- get someone to babysit for a weekend. Gt a decent night sleep and do something funwith your wife. She'll appreciate it more than you think!

- most of all: try to enjoy the little moments... Her sleeping in your arms, on your lap... They grow up so damn fast you wouldn't believe it!

Best of luck!
