Julian absolutely loved the dinosaurs! In part from watching "Night at the Museum". I think he could have stayed in the main dinosaur room all day. We also visited other exhibits there, but nothing else made such a great impression. Julian did not enjoy the rooms filled with dead and stuffed animals. And there were a lot of those! That was a bit too creepy especially for a three year old. We left the museum with a giant poster of dinosaurs and tired feet from a whole day of walking in Berlin.
Julian also swam everyday while we stayed at the hotel. I had taken him baby swimming for nine months, but he hadn't really swam much since then. Last time we were at a pool he had no interest in swimming and I figured it had all been a waste of time and money. Luckily, the pool in Berlin was the perfect temperature (I think that had a lot to do with it) and he took to the water like a duck. He's really confident in the water now and we all can't wait to go swimming again.
