Need help coping with a big baby

Jane

I was mentally prepared to have a small and petite baby, especially since I and all my siblings were small. Because of complications she was almost 11 lbs at birth and now it’s been about 3 months. With that being said shes pretty, and as adorable as I would’ve always hoped and shes smart and strong but she looks like she’s 6 months old. And I still can’t get over the fact that my 3 month old looks double her age. It makes me feel sad and depressed that shes not tiny in any sense of the word. And even though I keep telling myself maybe she’ll have a pause in growing and maybe shell stay her size till she’s actually 6 months, deep down I feel like I’m just lying to myself. Does anyone have any good coping mechanisms to help me get over this?
