When our first grandchild was born, her mother was a single mom and not responsible. But she did work full time. I worked also, so I took full responsibility for our granddaughter an she lived with us until she was 4 1/2yrs old. Yes, I gave up a lot, hired a womam to watch her when I worked, my DH also helped and I did not get much else done. But she is 28 yrs old now and that bond we have will always be there. By the way, my DD got married and her husband said he would raise our GD as his and he did. It was hard to let her go. You won't regret doing this
