Buying stuff

I don’t know if I have a problem or what but I always feel the need to buy things. Like I always feel like my baby girl needs more clothes and what not. It’s kind of like an addiction. She is 6 months old right now and has a fairly big wardrobe, she has 2 coats for up to 6 months, a coat 12-18 months and a fancy 12-18 month coat and a snow suit for up to 12 months. I keep obsessions over the fact that she doesn’t have a coat for the gap between 6 and 12 months. She’s tiny so her 3-6 month north face coat still fits great but what if it doesn’t fit in a month or 2. All I can literally think about is buying her a new coat. It’s like an obsession. Is this normal to always feel this way? Like if it’s not the coat it’s pants or sweaters or dresses or clothes for my older child. I fixate on things until I get them then I feel like a weight has been lifted.
