Since DH and I have had our girls, my mom can't seem to stop herself from questioning/commenting on/criticizing our parenting. It was so much easier to avoid when we lived a state away. Now that she sees us a few times a week, and she volunteers at my work, the comments are much harder to avoid.
My oldest started pre-school this year. She catches the bus from my office. We sit in the lobby of my building, so she's only outside for the time it takes to get to and from the car. Since my mom works close by, she often comes over before work to see my daughter.
DD is tall and lanky, like my husband. She doesn't have any extra "insulation" on her. It's getting cold here in the mornings, and I make sure she is dressed in layers. She usually has on a t-shirt, long sleeve shirt, cardigan, a hooded fleece coat, and a little cap. I have gloves in her backpack, but she usually doesn't want to wear them.
EVERY morning, my mom comments about how cold DD looks/feels. If DD has taken her cap off in the car, my mom will look at me agast and say, "Don't you have a hat for her to wear?" If she holds her hand to walk into the lobby, she says, "Do you hold on to ice cubes every morning?" Then she looks at me and says, "Where are her gloves?" My mom even went so far as to buy DD several sets of new gloves so we could keep a pair in the car "In case your mommy (me) forgets to put them in your bag." She's also gone and bought her new jeans (because the pants/leggings/tights DD usually wants to wear "aren't heavy enough to keep her warm.")
I think she means well, and doesn't see how I could interpret it as criticizing my abilities to take care of my child's needs, but when I try to calmly mention that I've got the clothing situation well in control, and I would never let her go to school in clothing inappropriate for weather conditions, my mother gets upset with me!
