Yes, in the US you can buy 500 ibuprofen tabs for like $8. Here you will pay €5 or so for about 20 tabs.
Regarding children's motrin and stuff: This depends on how old your kids are. If your kids are very young and it's hard getting syrups down them, i would strongly recommend bringing the concentrated versions of both motrin and tylenol for infants. If your kids are older and able to take syrups, there is a great strawberry tasting ibuprofen for kids called Antalfebal (or something like that) available here. As far as the cost, it is relevant because it's a bottle of syrup and kids don't take it as often as we do, so it doesn't matter how much it costs... i mean, it might not be worth taking up your suitcase space. On the other hand, the children's tylenol here (called tacchipirina) is horrible tasting... so that is up to your own judgement. My two yr old will take a 1/2 tsp of this if it's mixed in 8 oz. of milk. Otherwise, she won't get near it.
I have never seen maple syrup at Lidl, but I have seen it at E.Leclerc and Conad... you can find it surely. It's not cheap, and it's always the real syrup, never the aunt jemima's style. In any case, this all depends on what city you live in. In Florence and Rome i know there are lots more things available than on my side of the country...
Here are some things I always bring with me:
1. Marshmallows
2. Corn Syrup
3. Pecans
4. Dill Weed
5. coriander seeds for planting, if you like asian food, you can grow your own cilantro
6. bbq sauce
7. good old baking powder (they have something similar here but it doesn't work the same in your american recipes)
8. molasses
9. vanilla extract (not an essential - again they have something similar but it's not quite the same)
10. ziploc bags of all sizes. italians do not ziploc.
11. those disposable thermal heat packs for your sore muscles or cramps.
12. dried cranberries. you can even reconsitute these and make cranberry sauce at thanksgiving.
13. flavored coffee cream
I don't use Crisco or Miracle Whip, but just an FYI these do not exist here.
Here are some other notes, which I have copied from a previous post I put on expatexchange.com
Enjoy
Some tips for living here, especially if you are in a small town:
1. Realize that lots of things can be done without, lots of foods can actually be made by hand (e.g., pumpkin puree, coconut milk, curry paste, chicken broth... all things that US expats are used to finding in a can).
2. Learn how to drive like an italian. they are scary, but they are good drivers. They are defensive drivers (always looking out for possible danger), and they are offensive drivers (always creating a possible danger). Get used to it and don't cringe. Rules rarely apply.
3. Nothing can be accomplished in just one day. Do not make yourself a long to-do list and expect to get it all done in a day. You will find that bizarre shop hours, unexpected closures, long lines, total inefficency and just plain red tape will slow everything down and you will have to do some of it another day. You will not leave messages and have people call you back. You will call and call and call again until you finally find them. This will take up lots of your precious time.
4. Customer service has just recently become a concept in Italy. If your phone or internet gets cut off unexpectedly, don't expect a repair in less that 5 days, and don't ever expect a refund.
5. You may have to wash yourself without water in the summer, especially if you live in a tourist town by the beach. The hotels will get all your water every evening.
6. Doing laundry will take you 2 days instead of 2 hours.
There is lots to enjoy in Italy, but most things are not based on comfort, convenience, or service. It's another world.
