First off, I would not necessarily recommend 9 months as a good age for traveling solo with a baby. Offspring was much wigglier than a few months ago and also has started to experience separation anxiety so in an unfamiliar environment he wanted to be held approximately 110% of the time. Like, to the extent that it was hard to put on pants because he wouldn’t let go for a millisecond.
However, we powered through and of all the international locations we could have chosen, Buenos Aires was probably the best choice. Stroller accessible, only a 2.5 hour flight away, safe... We also took it pretty easy schedule wise which helped. We walked Recoleta and saw the cemetery (and the very anticlimactic tomb of Eva Peron), we did a short (and wiggly) wine tasting, we very briefly watched a tango Milonga (meetup) until Offspring got too wiggly again and we sampled the gritty neighborhood of La Boca.
My overall impression is that Buenos Aires is very liveable, if cold, and that Argentines don’t like kids nearly as much as Brazilians. But we had a good time nonetheless and I’d highly recommend a visit if you want to eat well, enjoy European-style architecture, and practice being very sophisticated.
Surviving this trip also gave me a boost of inspiration and confidence to try more travel, hopefully within Brazil this time.
La Boca again (it was seriously cold that day - as in it could have snowed - so we only stayed an hour or so but I'm glad we got to see a different side of the city than fancy Recoleta
Recoleta cemetary x 2 - I liked the architecture styles here but didn't take many photos
Eva Peron's tomb - see what I mean? Underwhelming
I loved all the French-style architecture
And baby just loved goofing around
