Am I in the wrong!?

Every since I went into labour (2day labour) I’ve had barley any sleep at all. Every night I been getting around 2hours sleep if I’m lucky! I have a 3week old and a toddler so life is pretty much on the go non stop.. I know this is pretty typical but my kids dad is starting to wind me up. Since the moment I got home from hospital my toddler fell ill with hand foot and mouth then the kids dad got it so he was sort of dealing with our toddler during the days and I was dealing with our newborn to try and prevent our baby from getting the illness as well. Anyways our toddler sleeps through the night so my kids dad was getting a full nights sleep through the night for about a week/2 which I understand he couldn’t help with the baby cos he was also carrying the illness but now everyone’s healthy again and I’m still functioning off 2hours a night while dealing with our newborn and toddler all day while he’s at work and last night he promised to let me sleep and get at least a full nights sleep while he dealt with the baby but oh no that didn’t happen at all. He done the bottle feed at 2am before we managed to go to sleep then at 5 he didn’t wake up to the baby crying so I woke him and asked if he was gonna deal with the baby but he was in a hump. I ended up having to get up change the baby make the baby’s bottle then share the feed with him because it was to much for him to do it himself! I didn’t say anything about my supposed “full nights sleep” as what was the point he was half asleep and I wasn’t trying to argue 🙄 then this morning baby’s and toddler are both up and awake surprise surprise who’s asleep and who’s awake me. I wake him up and ask if he’ll sort the baby out as our toddler was laying in bed still watching Toy Story so I knew I could maybe squeeze in a quick Power Nap before he was up ready for the day but my kids dad decided to wake up again with the hump because I asked him to sort the baby’s bottle etc and then he handed me the bottle and got back into bed so I switched and told him it was out of order that I’ve had no sleep at all and the one night he promised i basically was awake and doing most of it anyways and he said that it was my problem I should of stayed asleep and I told him how the fuck can I stay asleep when u don’t wake up to the baby and then ur asking me to do 100things because u can’t hold a baby and make a bottle at the same time 🤦🏻‍♀️ he then took the baby and the bottle and was basically ranting about something god knows what and then had the cheek to tell me our toddlers hungry go make him breakfast (like I wasn’t already planning on doing that seen as I do it every morning and deal with the baby at the same time so why can’t he do that!?) but I’m not a dickhead I’ll get up make my toddler breakfast I’m just annoyed that he’s not even doing the bare minimum atm just moaning and making promises that I can have at least one nights sleep and then falling back on that promise getting in returns “I’m tired to” like mate I know ur tired but you have basically had an easy 2weeks I been struggling I’m just asking for support without having to nag or beg u for it. Just feel like shit honestly i honestly feel so alone atm doing it on my own with someone there who could and should support me but yet feels like they aren’t there as I’m doing it on my own.
