K.,
Here are a few different idea's I have done through out the years with my 3. Happy Birthday to your little one!
I took a picture of my daughter in her dress that she was going to wear on party day.Then I went down to 1 hour photo had them blow it up to and 8x10 { you can do it bigger if you wish}. The you can go to a cheap store ex. ($ store) Buy a 8x10 frame and put in the picture but leave the glass out. Then during the party you could create a lasting memory for you and your child by having guests sign birthday wishes on the picture matte that you can later frame. Display this on a plate rack and place photos of your child on the table with it. Offer colorful pens for the guests to use. Include photos that showcase him or her throughout their first year. {BIRTHDAY WISHES}Ask guests to write birthday wishes for your one-year-old on slips of paper that you can keep in a bottle and open on a 16th or 18th birthday.
OR
A Birthday Garden
Plant a tree or flower that will bloom or multiply each year around your little one's special day, and mark it with a little plaque or sign, if desired. Then, make a yearly tradition of photographing your child by his birthday garden.
For Winter Babies... Plant holly, flowering jasmine, or crocus.
For Spring Children...There are many flowering bulbs, such as daffodils, lilac bushes, or tree peonies.
For Summer's Wee Ones... Celebrate with roses, iris, or hydrangea.
For Autumn Tykes... Clematis, Japanese Maple, or Crape Myrtle work well.
