Am I wrong?

So I’m a stay at home mum (not by choice but due to Covid, going back on 2nd July thank god!) and my partner works, he’s a farmer but is going through a quiet spell, he doesn’t work every day and if he does he works from 9-4 ish. I do EVERYTHING. So look after our 9 month old (feed, bath, change, put to bed and just generally watch him all day) as well as all the washing, cleaning, cooking etc. When my partner comes home he sits on the sofa on his phone watching tv and doesn’t move until he goes to bed. On his days off he spends time outside on the farm (not essential jobs as the animals are all out) or goes fishing. Our 9 month old has recently decided he’s wanting a bottle in the night again, as well as waking up because of teething. I’m the one that gets up in the night regardless of if he is working the next day or not. All I ask of my partner is for him to get up with our little one on his days off (he generally wakes up between 7-8am) for a couple of hours so I can have a bit extra sleep to make up for what I lose in the night. Might I add I’m also 14 1/2 weeks pregnant so I’m exhausted as it is!

Am I wrong for asking him to spend a couple of hours in the morning looking after his son on his days off?
