I tried to keep the day very low key so he didn't get too overstimulated and just planned a very little celebration for him in the evening. Thank goodness the boys were in school. The day was going quite nicely until they got home. They were so excited about it being his birthday that they were a bit (and by "a bit" I mean "a lot") overwhelming for him. They had him so keyed up in just a couple of hours that he was a complete wreck.
We had to take a break after opening his presents. I sent the kids downstairs and spent some very quiet time holding Koen and helping him relax. He was finally ready for the last half of the party.
He didn't know what to think of the cake at first. I don't think he like the feel of the frosting, but once he got through the frosting to the cake it was all over. He had a blast with it and I couldn't believe how much he actually ate.
