Hard being a mom..

It's so hard being a first time mom. My husband has a 14 year old, so he thinks everything I do is wrong. I'm my daughter's provider 98% of the time. When she wakes during the night I have no help. He tries to help, he will sleep with Lillie 2 days of the week. It just always hurts my feelings that he doesn't see the down side, he only sees the happy baby. When I text saying she is giving me a fit and I'm tired (she still wakes every 2 hours at 5 months) I get you only work 25 hours a week and she is always good for me.. You spend 3-4 hours alone time a day with her! I'm exhausted.. When she wakes for her 4 am feed, she gets restless.. She tosses and turns the rest of the morning, I never go back to sleep. It's amazing when your husband makes you feel like a shit mom.
