Inexpensive Children's Christmas Gift Ideas?

I'm on a extremely tight budget for Xmas gifts this year. I have only got $60 ($30 each child) to spend on my children. My son is 6 years old and my daughter is 4 years old. My aunt already bought them some DSs and games, train tracks, a cupcake marker, and one of those Barbie heads where you can cut their hair off.

I'm kinda unsure now what to get them. I would like to get them something that will be meaningful and will remind them of mommy and how much I love and miss them and that's good for their mental and physical development. I only get to see them once a month for 3-6 days. I'm dealing with money and personal issues, so they can't legally live with me right now, but I'm working on having them back in my home again.

Here is a list of gifts I'm thinking I might them:

For my son:

anything Spideman and Thomas the Train
a nice soft fleece blanket, the one he had as a toddler that I bought him, just something he can cuddle up too and it can be reminder of us having cuddle time.

For My Daughter:

colored rainbow nail polish, especially want to get her purple cuz its her favorite color; she can mix the colors on her nails cuz she likes doing that

light colored makeup
gold earrings (If I can borrow enough money to buy them.)
stickers
I was also thinking of making something for them as well, just in need of some creative crafts to make for kids ages 4-6 years. I also want to get and make some something they will actually use and need and like.

Any good suggestions would really be appreciated :D

I know Xmas is already over, but was thinking of buying gifts on Boxing Day to save money too and I don't get to see them until early January.
