I feel delighted thread starter(Louzhu) has thought this question through and discuss it before you really give birth to a child.
Love is the most important thing in the world, especially love from the family, love in someone's childhood. I think your slight love deficit or affection coldness comes from grow experience.
If you can't give them a happy childhood, physically and mentally, I don't think you're ready for that, maybe you need a destined man to rebuild your love ability, make you desperate to have and raise your own baby.
I'm talking about a normal society, not to mention a society where government exhaust you with tons of headachy problems of Hukou system, high price real estate, education, medical security, food security, overloading work, instead of subsidizing the family of children
