Not odd at all. Sounds lovely. I wish my kids lived closer sometimes - they live around 25-35 miles away, because I live quite rural. I do see them 2 or 3 times a month though, and speak most days on twitter or facebook.
The people poo-pooing you are probably just a bit jealous.
Your family sound proper old fashioned and it's lovely! 
The days of people living near to each other (like they do on soap operas) is quite rare, as people move away for jobs etc, or because they met someone at uni, and moved to the uni town, or the town their partner is from (or somewhere in between..) So I think it's wonderful when family live close-ish (and get on of course!)
Several of my neighbours aged 30-45-ish, have their parents, and a sibling, and also a few nieces and nephews, all within this village, and I actually quite envy them. All our family (what little we have,) lives abroad, or 100s of miles away - including our brothers (1 each,) who live overseas with their kids. We are lucky if we see them once a year. (Though we speak via social media on a fairly regular basis, and share photos etc.)
As I said though, we do see our (adult) children roughly 3 or 4 times a month. And we have several aunts and several cousins between us who we see about 5-6 times a year, who live 60ish miles away.
