Sorry this is kind of long . . . I have a three year old (1/2005), a two year old (12/2005) and an 11 month old (10/2007). Going out I get comments on a regular basis about me having my hands so full. One lady the other day just kept telling me she was so sorry for me. Another lady tried to tell me to stop having kids. Kind of ridiculeous but you learn to laugh. I am one where I have to get out of the house almost every day so I do everything with kids in tow. When we grocery shop I put on in the top seat and one in the basket. (When she was tiny we used a bumbo seat in the basket). Then the third had to stay right by me. If he didn't then he had to hold onto the cart the whole time. This arrangment is diffucult on big grocery trips but we got often enought that it works. If we have too much then the two year old gets the job of pushing the cart with me. They really like the responsibility. Costco is great having the double seats and the car shopping carts and safeway are nice.
At home you my be outnumbered but *most* of the time it doesn't make too much of a difference. There are those times when all three will be upset and there is just not enough of you to go around. That is really frustrating but isn't just being a parent that way sometimes? Though I have to agree three is much harder than two, at first anyway. My daughter is almost one and those first months were pretty tough but now that she plays with the other, they are so much fun to watch. Being so close in age they love to play together.
P.S. Get the taking thier long afternoon nap at the same time early on. You will appreciate the "you" time and the rest
