Traveling in Poland with an Infant

I'm from Poland and I can assure you that there are no special warnings or circumstances about traveling there with a small child. When visiting my cousins there, we went around everywhere with their small children (mostly by car though because it was just easier that way - not that public transport wouldn't have worked as well). It won't be any different than traveling in Germany or elsewhere in Europe. It sounds like you have the right approach about level of activity, and that's all that really matters here. If you have any particular products you can't live without, I suppose it's better to bring those along, but the markets in Poland should have everything you need (they have the same chains as anywhere else like Carrefour, etc.)

Agnes,
Thank you. Do you think Wroclaw and Krakow are two good destinations for first-time visitors? I'm trying to keep our destinations close together to minimize complex transit. We might then go to berlin, and then the south of Germany.

Sure, why not? I would also add Gdansk but that's way further out (all the way to the north). Poland has a fast train network between major cities. If you end up flying into Warsaw, it's definitely worth seeing too. There is a lovely park I could recommend there that I went to as a small child called Łazienki Park, kids love it because there are friendly squirrels and peacocks there and it's a beautiful place to stroll and just chill out.

Well, as a 15 month old, I'm not sure how much she will enjoy a park. We are really looking for sight-seeing or amusements for us, but hoping we can find some for us that allow her to ride along with us. And places to eat where she can also go.

Restaurants will have high chairs and the like, you shouldn't have any problems finding them. Just pick ones that aren't obviously for adults on the less-child-friendly scale (usually high-end ones or vodka bars, etc.). In most places where I've been, kids are welcome and not an issue.

We've done a lot of travelling with our kids, including when they were babies/ toddlers and visited Kraków when they were 3&4. We stayed in an apartment right off the main square and found the restaurants in the square to be very kid and parent friendly. At 15 months, your child should be able to easily blend into your plans, especially if s/he is easy going. I agree with the previous poster that having a park or space to run around is a good idea at that age. Our toddlers sat nicely in the stroller through museums and sites as long we timed well with naps, snacks and playground visits. Have a great trip!
