Hi there newaththis,
Firstly congrats, exciting times I'm sure!
Have to mirror the thoughts of MotherofaFather here. It sounds exactly like my own situation earlier this year (I own my own business and was the only one working from month 1 of pregnancy). If your work is project-based, I can imagine that you work the hours that are necessary and travel where needed to make sure you can financially provide - you shouldn't feel bad about it, thats the nature of the work and was the case (I assume) before you had a child.
It's awesome that you have family about and that you're not shirking responsibility at home in addition to doing your vocation. Be careful not to burn yourself out along the way.
I can't speak for your wife or your specific situation, but being a stay-at-home mum is/should be an all encompassing role. Take the mindset (if only for a minute), you and your wife produced your daughter. Having family about is a bonus, but not a prerequisite of being a parent.
Might be helpful to talk with your wife about how you can better share the workload together. I'd try making suggestions like if you are cooking preparing a few meals in one go and freezing them (to give you both a break when needed). That might free up some time for her to help on something else, perhaps? Or finding a mix like that, that works for you guys.
Remember, a successful relationship is where you're both going 110% to cater to each other, rather than I'll do 50% of this, if you do the other half. It sounds like your contribution for more reasons that one is going to be made of in a large part with going out and earning a living right now.
Best of seasons greetings!
Concerned Daddy.
