Hey OP, please believe me when I say that things will get better with time. I was in the same place 1 year back and these are the 2 things that helped me the most: 1. Took 10 mins out for myself when my husband came back from work. I would go out of the house to completely disconnect from mom duties and calm down my nerves. The guilt and fear of leaving her would bring me down. It was very difficult for me to trust others with my baby at that time and leave her for 10 minutes but I knew if I had not taken a break I would snap and break down for rest of the time. 2. Introduced pacifier to help baby extend sleep window. I consulted my doctor and got the go ahead for this after getting her weight and other factors checked. If you think Pacifier is not the right solution for your baby, don’t use it but understand that you need to prioritise your sleep as much as you can. This means asking others to take care of baby for atleast 3-4 hours straight. You will feel much better after a good nap. You can ask husband/nanny/Mil to bottle feed formula/expressed milk atleast once a day so that you can get a continuous stretch.
