We purchased our het albino, Sylvanas, in September on the 29th at the last minute (due to my indecisiveness) and in my newbie excitement I forgot to ask how old she was.

I was more concerned about what she was eating and my brain was only thinking about that, they told she was eating F/T hoppers.

Now I noticed her out of her hide nearly all day for a few days about a week after we got her home and figured she must be looking for food (as my cornsnake that I had a few years back would do the same a a day or two before his scheduled feed) but she wouldn't take her meal. So I thought I would try again a week later and again she just would not take it!
I looked online for various methods you can use to entice them, even getting my bf to expose the brain( ) that some sites suggested and nothing! She was just not interested.
So finally we went to the pet store that day and got 2 live hopper mice and when we came home my bf dangled one of the hoppers near her and she immediately took it.
So now we've been feeding her live hoppers roughly every week. I don't mind feeding live and always monitor her feeding.

Now the breeder says she was hatched in the months of May-July, she's not sure which clutch she came from as she doesn't remember me.
I just weighed her today and she is 136 grams. I also measured her and she is roughly 18-20 inches. Now I am wondering if May-July would be an accurate date? And if that is an okay weight for her? And I'm also wondering if the hopper mice are too small for her?
I just found this website a few days ago and after reading some threads I am getting really paranoid that I'm not doing things right.
She just went through a shed (which went very smoothly) and I was planning on going to get some mice today and before I go wanted to make sure hoppers were fine or switch her to the next size.





This is probably roughly the size of what she is eating:
