A big wheel!!! Totally a big wheel!!! My son turns 2 next month and I was SOOOO excited to find out that they do sell them still, at Target. There's only 2 now (the original and the princess) but there is NOONE my age that didn't have a big wheel, or that couldn't tell you every detail about their specific one. It's lower to the ground, and wider, so it's a little safer than a traditional tricycle, and the seat adjusts back so it can "grow" with the child. It's totally what I'm going to get my son for his 2nd birthday next month. (I know, I know---some people would think I'm sticking my child with something that is fun for ME but that's silly---he's only 2 and this is your last bit of time when you CAN have a say in what they like, lol). Another thing: even though I had a "regular" bike that I was riding without training wheels at 4, I rode that big wheel just for fun for YEARS. I (and my friends) only stopped riding them when they finally died under our weight (even though I used my 10 speed bike for "distance" riding). Times have changed yeah, but fun is...well....fun.
As for birthdays: we threw a huge party for his first birthday (a "come meet the baby" AND a first birthday party since we live out of state from everyone we knew), but this 2nd party will be very laid back, and probably will be until his first "school age" birthday. The pumpkin patches will be open during his birthday, so we were planning on going to the Flower Mound Pumpkin Patch (check it out online) with just us, maybe a couple friends will tag along. He can do a hayride, decorate a pumpkin (we'll do his with markers since he's too young to have a knife or candles), play at the patch, maybe take him to ride a pony somewhere, and they have picnic tables there so we can have a nice family picnic and I'll make a birthday cake for him to eat there. I say it's all about the family these next couple years, and then the school friends and hoopla begin a little at a time. Hope you guys have fun with whatever you decide!
