I’ve been with my partner for just over two years and we have a 4 month old baby girl. He’s been back at work doing 40 hours a week since she was around 2 weeks old, his shifts mainly consist of him working until midnight and him not getting home until around 1am. Our daughter has been very “difficult” since she was born and we’ve struggled with her mainly on a night. I found that his shifts weren’t helping - I was exhausted from dealing with her all day & then him coming home late meant I had to deal with her for most of the night. I felt like I was being a single parent so we had a conversation and he went to his manager and got his shifts changed so they were more “daytime shifts” for a while these were working. He was getting up on a morning feeding and changing our baby going to work and allowing me to catch up on sleep whilst he worked. By the time he came home he wasn’t tired and was able to do more with our baby. He’s now back to doing the midnight finishes and I’ve found everyday he complains about being tired, he doesn’t do anything with our daughter because I’m doing everything. I keep getting the feeling he doesn’t want to be around me let alone our daughter. I’ve just done 6 days straight of having our daughter all day and then all night & he’s finally got a day off tomorrow so asked if he’d deal with her tonight and it’s caused an argument because he’s tired & he’s not had a break and wants to wind down. Because he’s not coming home until 1am we aren’t getting into bed until around 3am due to the fact we need something to eat, I’m usually giving our daughter a last bottle around 1am and then he has to relax, when this is happening he’s not getting out of bed until 11am the next morning and then he’s up and out of the door for 2:30pm ready for work. I would go to bed early but it means him not seeing his daughter because by the time he wakes up she’s probably had a bottle and is down for a nap, by the time he’s leaving she’s probably having another bottle which I have to do because he doesn’t have the time due to him getting ready for work. When he comes home from work his first thing he wants to do is cook food he never seems to be interested in coming in and spending time with our daughter. I’m not bothered about him not spending time with me as I’m used too it, but feel bad for our baby girl. In the 6 days I’ve had our daughter I haven’t slept, I haven’t eaten properly & I’ve basically been awake for 18-19 hours a day. To make matters worse she’s currently in the early stages of teething so I’m already struggling with her not sleeping she’s now at the stage where she won’t settle, she doesn’t drink her milk and literally won’t go down and prefers spending all day in someone’s arms. Whilst he’s at work I’m the one who’s doing the cleaning, and making sure that the house is clean, the washing is down, the shopping is down etc.. when he cooks he doesn’t tidy up so I have to deal with it on a morning. All I’ve asked is for one day and night where I don’t have to worry about her and it’s caused an argument. I feel like everytime I ask him to do something to do with our baby he finds every excuse to not do it. Am I a bad parent for wanting just one night of being able to sleep. Should I have more sympathy at the fact he’s been working all week ? I feel like I’m being a terrible person just for asking for a break.
