My 21 month old son just loves to party and he hates to miss anything.  However, after the excitement of Thanksgiving day (and his inability to take a nap) he was fussy and ended up waking up every 2 hours all night long.  It was quite a price to pay to enjoy maximum amount of time with his cousins.  Jen's suggestion of maintaining the routine is really important and I have found that alloting extra time for naps and slightly earlier bedtimes has really helped Ethan from getting totally overwhelmed with all the hustle and bustle.  Good luck and follow your baby's cues.  If he is getting tired, remove him from all the excitement.  You'll be so glad you did.

I agree with jenlemen's answer. Try and keep your routine. You may be tempted to delay the naps because you want to visit with relatives and friends, but don't. Also, try and have people approach your son one at a time and not crowd him. It's better if you wait until your son approaches people when he is comfortable enough.

helloooooo there, my sweety is just 2, I found that keeping her routine was is essential,specially nap times. I usually read quiet stories to her to slow her down a tad first then make sure she has her nap. I also try to keep her food as normal as possible....grandies do like to spoil I know but I find limiting the treats is very important.generally they seemto come through with flying colours as long as they don't pick up a bug when away from home.Breanna did then promptly cut two new incissor teeth at once one for her one for me teee heee

do you think you could be worrying for nothing? all 2 year olds will get excited, but nothing a walm bath and a cuddle from mum cant fix.dont stress to much and just have fun!! goodluck i hope you all have a ball!!

i think it helps to try to keep your schedule whenever possible.  your family will understand more than likely, and you might enjoy the break for yourself as well.  stealing away for even an hour to a quiet bedroom where you can sit and read books or nap helps a lot.  reserving the right to say no and to choose the activities that are really work for your child makes a difference, too.  the most important thing is to build in downtime every day and to make sure that you observe bedtime and regular mealtimes as much as possible.
