Hello and Welcome! As you develop your own early learning philosophy, you will find that teachable moments are around every corner! We're glad you joined us!
Typically, parents start with one subject and then build on it. What would you like to start with? For teaching a second language, many people do "one parent, one language," you can google more info on that. You can introduce reading in Portuguese at the same time that you are introducing reading in English, your baby will not get confused. If you're interested to go beyond a second language, try to source a babysitter that is multilingual, it kills two birds with one stone. You get a date night and baby learns--win/win!

You can also look for local playgroups of parents that are native to other areas.
For Portuguese, I haven't heard of a whole lot of resources (at least not on this forum) to teach it beyond the community files in LR, so I'm pretty sure Little Reader will be your best bet. You can check the Little Reader Library above for Portuguese downloads and make your own as well using the software. The possibilities are limitless! Imagine one year from today, your child will most likely be reading in 2+ languages and possibly even decoding novel words phonetically...how cool is that?!

For hands on things, you can create your own curriculum but it also sounds like Montessori learning would be right up your alley. I believe that programs like Little Reader introduce information so effectively and efficiently, it only makes sense to take advantage of that. However, you can still balance visual flashcard/screen learning with plenty of concrete, discovery type of activities, capitalizing on the best of both words. Google "Montessori Baby Blog" or "Montessori Baby Activities" or check out this link, it'll keep you busy for a while.
