Not unreasonable at all. The first few days are a complete blur but also the best days. My SS came to us the day after I got out of hospital and I hated it. He came to us ill so instead of being with us for 2 days it was 9. I had all of my HV appointments and he just sat in the room staring at them! It was a horrible experience and I still have some resentment towards him and my partner because of it
It's not unreasonable at all. My SD was around a lot when our daughter was first born, when we'd barely get to see her usually, and whilst it was lovely for a short period of time it got way too much. I honestly couldn't manage more than a couple of hours at a time.
I still regret not just having the three of us when we first got home. I had to stay in hospital for five nights after birth as I was unwell. We weren’t meant to have SD on our first night back. I don’t even remember the reason why we did end up having her. I wouldn’t say she made it unpleasant but I do wish I had of had just me, my partner and baby for night one. I was recovering and tired but we had a six year old to entertain.
We didn’t see my stepson for 3 weeks over my due date because we knew if I went into Labour she wouldn’t answer the phone to take him back and my husband would miss the Labour, also stepson had a constant cough we didn’t want newborn getting
Not unreasonable at all, you should be able to enjoy the time the three of you when you first get home and you sound like you will be very inclusive of stepchild so I don’t think you have anything to worry about.
You only get to experience first baby once and you will be recovering, it's not unreasonable at all
