I planned on 2 kids now I'm not so sure...

I pictured myself with 2 kids close in age but now that I have 1 I can't imagine having 2. I'm often tired and hungry. I miss my freedom. I miss myself and my body. I love my little girl she melts my heart, but I'm so exhausted I don't think I ever want to care for another newborn. But then I feel selfidh that she won't have a sibling. I will obviously give it more thought and see how I feek when my little one older but right now I don't think I can have another 🙁
