P.K.
Well mine being all,a year apart flew close together. Eventually my husband and I settled into a routine. My husband retired at 59 after 37 years on the NYPD . I stayed home for the middle school/high school years. We started to travel, they got married, then started having kids! It all seemed in the blink of any eye. Are we "empty" now, no. We babysit our 8 month old granddaughter five days a week and the others on an as needed basis. So enjoy the quiet, settle into a routine and guaranteed right before your eyes, you will be babysitting grandchildren lol.
