Easter Basket ?

Okay so i'm sorry if I sound dumb but I wasn't raised with these customs but I'd really like to do them for my daughter , 
Okay so whats with moms making these " easter baskets " for their kids ? I think it's really creative and i'm not sure when easter is but since my baby is due this month i'd love to make her one but before I do I would like to know why mom's do this ? What's the meaning behind it ?
