No family around

So I have a four month old beautiful baby girl. She’s our rainbow baby. Anyway, I don’t know why but I can’t shake this feeling of feeling bad for her because we don’t have any family around. We moved here in 2015. My husband is not close with his family at all so that really only leaves my family. My parents don’t live here they retired in FL and my brother sis in law and there kids who are 9 and 14 live in another state as well. We FaceTime etc and get together occasionally but every time I see babies close to her age with cousins and aunts and uncles all around I feel bad. My mom tells me not to feel bad for my daughter that she’ll pick up on that as she gets older and it’s not healthy for her which I know. Is anyone else in a similar situation? I just want her to be happy and I worry she’s not or she won’t be bc she only really has me and her dad. Maybe I’m making a bigger deal out of it then it is. I’m also 40 and I don’t know if we’ll have another with what we’ve been through so that makes me sad too if she’s an only child. Here’s a picture of her. I love her so much.
