this must be your first child! how sweet!
i know its supposed to rain soon, but you know how california is! it stays fairly warm! keep your eye on the weather channel and im sure things will work out fine!
our third baby is our only winter baby and he will be one year old on february 3rd. im going to have our families come over the saturday before his birthday and i wanted to take them over and ride the fairy to balboa island and walk around town and then come back and have some cake and ice cream or maybe even go to the dollar theater in irvine. if a good movie is playing! all of these are very inexpensive. if we do end up paying for everything it would only be about 50 bucks for everyone. but my family likes outdoorsy things, we will probably end up going to the beach to play as well.
for our first we had a little party at our own little home and it was great even though the living room was filled with my and my hubbys friends!
with our second childs first b-day my mother had it at her house and it did pretty much become her party, but i didnt mind because i had my teeth worked on the day before so i wasnt really in a hostess mood. i did make the cake (a princess castle) it was fun.
best thing to do is to weigh the pros and cons and if you want to have it at your mothers then definitely voice your need to make it the way you feel your baby will enjoy it the best.
is there mostly going to be adults there? i liked the idea with the game about the baby for the adults, that was cute!
also if there are going to be lots of toddlers or small kids there, i know homemade playdough is sooo much fun for them. at my daughters second b-day party we had three tables set up for kids, one had homemade playdough in four colors with wooden rollers and kid safe knives. the second had a huge thing of crayons and lots of construction paper and things like stickers and glitter paint, etc. and the third had healthy snacks like veggies fruit and goldfish crackers and cheese sticks, etc.
at my sons fourth b-day we had a bubble party, we set up two bubble machines and handed out little containers of bubbles and threw a bunch of balls and balloons around the yard for them to play with. it was great!
just some ideas!! i hope you find something awesome to do!!
