Hi,
so I read through the comments and I have to say that there is not a lot of practical advise as to how to physically manage it alone.
To be honest shame on you who wrote "You decide wether you can do it before having a baby" that has got to be the dumbest advise I have heard from a parent to another parent in a long time. Should have just kept quiet.
I will give you some practical advise below, for background, we have no family available, my parents live 2000km in NorthEast direction from us, my husband's parents live 2000km in Southeast direction from us.
My parents are in their 70s and my mum has point blank said she does not have the health or energy to mind a baby and my husband's parents are also 70 AND minding other grandkids because he is the last one to produce offspring from his siblings.
We both have been quite career focused before children, quite introverted, neither of us have close friends that could help practically. Somehow we have always been those who help others, who go to birthday parties and give out generous gifts to our friends and siblings, my family is emotionally distant and does not help even with money.
Before having my first child I was in an industry that demands far longer working hours than nursery covers, so purely putting my first born into a nursery and continuing as usual was simply impossible. My husband is self employed, he runs our family business. After I had my first I moved on to help my husband run our family business with my own professional certification, commercial network and business management skills. Our business has two areas of operation, we are employers and we have people working for us. If we do not work, nothing happens. Now I am pregnant with second and my second maternity leave will probably offcially be 3 weeks and unoffically 5 days because I still have to pay people's salaries and review weekly work etc, my husband does not have the qualifications to do some things I do.
After our first was born my husband was home for just a week untill he resumed work, he did no night wakes and to this day does not have the stomach to change poopy nappies. I work, we are not yet in nursery, I look after the household, cook and mind the child whenever he is not available, which is pretty much 6 days a week between 0600am and 0600pm. For periods I have had to mentally support my husband as running own business can be very stressful and sometimes he cracks under intense pressure, sometimes he was no shoulder or wall to me and I had to bear the burden for both of us in this sense.
So... now you know of the extent of how alone one can truly be, but hey ho, it clearly wasn't that bad because we have second one on the way.
Practical solutions I applied to get through it all:
-You can join a pregnancy group, with babies due in the same month, you will have people to relate to, people to give practical advise, as with the first kids we never really know what we are doing and other mums are the ultimate source of information and intellectual support. Many of them will be in your shoes at exactly the same time so in terms of mental and emotional support, if the father works long hours he will not be able to relate to you as much as you would like and there will be resentment and there are periods of time when it is best to use mum friends as hard shoulder to hold your flag mentally.
-I went to baby groups, but I am introverted and I don't make friends easily, I find it difficult to make friends and small talk in baby groups, I am an outsider in most places I go to, so some baby groups made me feel more lonely, for me they were great to have a purpose to go out from the house when the baby was still small as it can be difficult to find time and motivation to put clothes on when you are super sleep deprived, but if we give in to that it is counter productive. If one baby group doesn't click for you, keep looking and go to others, one of them will be a good way to spend time. I did not make any real friends in these groups, I did meet some interesting people, but it did not turn into a friendship outside of it, so you can't really bet on the groups to find actual connections there.
-It's difficult to manage the daily when they are small, they don't want to be put down. I made a schedule of activities for my baby since he was tiny, rotated them, to ensure I have time to wash my face, brush my teeth because even that can be a task with a newborn. I stuck to this routine every single, like I would put the baby in the baby gym, then I would have a sensory corner, then a different corner of toys, basically rotated him around the house, I used to put him in the baby bjorn, when he was training to sit I got him a trainer seat and gave him different toys.
-Now I have a home office so I have to have him chill on his own and mind his business while I deal with paperwork and emails, the house is his lair and I have the ballpit literally behind me when I am sat at my desk, making the space also for the baby makes all the difference in the longer run.
-Make sure you make room for the child in every place where you will spend some time (like living room, kitchen, bedroom) they need to have something to do, and so that you could keep them nearby. I have a triptrapp and when I was cooking I put him in the newborn attachement and kept him next to me, now he has a learning tower and is playing in the sink while I food prep.
-Take your showers when partner is home, make them long, that is going to be your time to wind down, especially great for the evenings, makes a massive different to how we feel as people.
There will definetely be some people who say "some babies are just needy" well, yeah, but I will not know about this one, because he can keep himself occupied and he is a confident toddler which makes a massive different to how much I enjoy his company when I do not have any time to give him attention. It is better to try practical approach and work with the environment than just hope that making friends in groups and venting in chats is going to get us through.
Good luck <3
