To feel resentful of DP wanting to nap

[skywalkersweetie]

Just looking for perspectives as to whether IABU or not.
DP and I are both full time students. I also seem to be the default parent to DS and do all the night time feeds and early mornings.
DP just took DS for an hour or so so I could nap as only 5 hours sleep last night and I was working this morning (grandparents took him for 2 hours, I did the rest of the morning).
Now feeling irritated at DP for immediately jumping into bed for his own nap as soon as I took over DS. Sounds like I'm BU but DP only gets up at 9/10am every day due to staying up late of his own accord, playing video games, reading etc. again he never does nighttime wakes as DS is quite dependent on me and the breast.
AIBU to think DP shouldn't need to nap during the day if he's only been up since 10am, slept through the night and isn't unwell? Feels like I'm talking about a toddler 😂
I just want him to get on with his studying as he will be the breadwinner for us so needs to do well and get a job!

Jesus he sounds like a massive man child. Why have you just accepted your the default parent?? From now on a rota - DP you've got weds through to Friday, I'll do the weekend then we can alternate the other days. Or whatever works. Don't be a doormat.

Exactly what Llamas says. Put your foot down now or this will never change!

Agreed! I guess breastfeeding and separation anxiety mainly, but also my course is less intense than his masters, and has only just started after my Mat leave, so just getting into a routine.
He reckons I'm just being spiteful for not wanting him to rest after he [so graciously] looked after his own son for a bit. Just wanted some reassurance that I'm not being spiteful and a psycho for wanting a partner rather than a toddler!!!

You're not wrong he's being a massive child.. is he always so tit for tat about everything? He clearly didn't even need or really want to nap but because you had a nap then it's his turn. How old are you both? I can't believe really either of you need to nap- and I have two kids under 5 and work full time 🤷 so I get the tiredness. But anyway he's being a child, time to nip that I the bud.
