Partner wants me back to normal immediately and I'm not having it

This is a rant but I need to get it out. My wife keeps hinting that I should stop taking so much paternity leave and "just come back part time" or whatever. We have a 4-month-old. I was planning to take the full 12 weeks and honestly I feel like I'm finally starting to get the hang of this dad thing. I'm not trying to be a deadbeat but ngl it feels like she wants me out of the house. Is she bored of me? Are we in trouble? Or am I being dramatic? We've been weird with each other since the baby came and I hate it.
