Baby is eight weeks old (velcro baby) and I'm drowning trying to keep ontop of the house etc and with no sleep.
The three step kids are here too for two weeks and I'm left with all the cooking etc and tidying for them , I used to do it but I just can't with a very young baby. He is screaming around dinner time so cooking is a nightmare. Honestly work was less stressful and I'm looking forward forward to going back asap.
Dp seemed to think he was pulling his weight and wants asking to do jobs and reminding. I don't have the energy to remind a grown man to feed/clean out his pets or clean the bathroom. Tbh when he's away for work and it's just me and baby it's soo much less work! I can co sleep and just not cook if I don't have the energy and do small bits as I go.
Just wanted to offer a big hug and
. Two years ago I was in an almost identical situation - even down to the step kids - and I won’t lie, it was hell. Sheer hell.
The good news is that it doesn’t last forever and it will get better. Sounds trite but it’s true. In my case I had to really put my foot down with my husband and have a lot of arguments in order to renegotiate the balance so that it was fairer.
He used to leave for work at 7am, leaving me to get three children - newborn, two year old and seven year old - fed, dressed and ready for school on my own. Including teeth, wrestling the little ones into shoes/coats. Then we’d get in the car and battle traffic for the best part of an hour to get to the SDC’s school. Baby literally bright red, sweaty screaming in the back the entire way. Just horrendous.
I’d drop the SDC at school and very often drive round the corner and park in the local Sainsbury’s car park in the furthest corner, away from everyone, put on a nursery rhyme CD for the two year old and feed the baby while silently crying my eyes out. And that was just the beginning of the day. I then had to do that journey in reverse in the afternoon to pick SDC up and then deal with all three of them until bedtime, when my husband would breeze through the door just in time to kiss them all goodnight.
After six months of that I basically told him I wasn’t doing it any more. He needed to take responsibility for sorting the SDC’s school run, and he needed to pull his finger out of his arse when it came to doing his share of housework when he was at home. He used to leave his dirty clothes down the side of the bed. I only washed stuff that was in the washing basket. When he moaned I told him to put his stuff in the basket then. He told me I needed to put a reminder in my phone to remind him to put stuff in the washing basket 
Things went nuclear, I was so near the end of my tether with PND and his ignorance that I nearly walked. I was prepared to. Eventually we found a common ground and he helped me make some changes to make things easier for me.
The youngest DC is three now and we’re definitely coming out the other side of it. I’m about to go back to work full time and am looking forward to it so much. I’ve always had high flying ‘career’ jobs with travel and stress, but that first year at home with my youngest was the hardest thing I’ve ever done.
I don’t know what the answer is. But it’s fucking hard and so under appreciated and supportive hugs and sympathetic arm squeezes to everyone in the middle of it right now.
