My nephew that is :) He is 2.5. My sister and I are only 10 months apart and are very close. We actually live only about two min. From each other. We talk on the phone and see each other several times a day most days. Therefore our children are very close as well. We treat each others children like our own. So my nephew Xander is now the baby of the family at 2.5. He has learned how to find my picture in my sisters phone and call me to ask if I will come and get him. Its so stinking cute! I have five kids and she has three and they are always spending the night with each other. Are you that close to your siblings and nieces/nephews? Would you be ok with your kids staying with your siblings so often?
