Another Baby?

I have this desire for another baby. When I had my daughter it was at one of the hardest points of my life, when I lost my father I ended up with PND and resenting my baby for 3 months she is the perfect, sweetest little girl and I couldn't love her any more then I do. Her daddy is amazing however is in the army and I am on my own most of the time.

I have recently had this burning desire for another baby but scared that I will go through the same resentment or PND again.

There would be a 7 year age gap and I am in 2 minds will it be fare on my daughter when my husband is away?

Has anyone been in my position with kids 7 years difference and a partner that's never around due to work?

Any army wives that have multiple kids with big age gaps?
