I hate when any one other than my husband or myself says "our baby" other than mil who watches her whenever I need her to (which is 10 hours a day 4 days a week and 4-5 hours 2 more days of the week) they do not have the right! do you buy her clothes/food? do you watch her? do you pay for a babysitter? no no and no SO no she isn't yours!! ugh!😠😠
