Ladies with more than one kiddo! Is it easier to have another baby when your first is like 3 to four? Or is it better to wait till they are about 5? Im not even sure we want more kids but I need to have that conversation with my fiance soon since we are looking at birth control options now. I think i might want maybe one more kiddo. Two more at the very most. But im not fully decided yet. But if we do decide we want more im worried about the kids not bonding because of age gaps and things like that. Thanks in advance.
