This one is small so it wont fit a lot of things, but you should know the necessities that you need to bring.
I don't have a small diaper bag so what I did is I use my bag as my son's diaper bag. I know it is not an actual diaper bag but why spend some money if you have something to use? It tends to change once in a while, whatever bag I'm currently using is also the bag that I use as my son's diaper bag. So I don't have a particular photo to show you. Because I use a lot of bag for this part. But a little example is the Louis Vuitton Hampstead bag. You can check it right here.
Just for some information my son is 6 months now, but you dont have to worry if you have a younger infant or if you have older one you can still bring this things and a little adjustment can do. You can either put some more things or remove the things you think you don't need.
Let's start..
