@yuliia OP, I am a FTM of a 3 month old.
Your wife having doubts and crying for any reason was me not long ago.
I wish cried more to be honest. I felt like I had to get it together because I was a mom now.
Felt more like a caretaker around this time. It was brutal and my husband, just like you, really helped me get it together. He actually got counseling a couple times.
The endless list of things you now have to tend to plus sleep deprivation, it’s a lot.
Around 8 weeks is when I began to appreciate my baby.
You both just experienced a life-changing event.
In the next couple of months, things will improve. The baby will still be running the show but you’ll be on the other side having made it. You’ll both look back and laugh-cry a little.
This is so hard, try to stay in the moment, and take it one day at a time because this is a just a blip. You guys got this, I promise.
