Update: She likes to go outside again!

Today was finally such a beautiful, sunny day!.. But something got messed up with our nap, don't know why.. And so we got to go outside only in the evening, sun was almost setting. Nevertheless, she liked it so much! It has gotten better and better, and now she again is totally willing to walk, once we go out, she is happy.. Today we took again as long toddler walk, as we sometime used to.

So maybe her not liking to go out was only a short period, connected with her being sick.
Which makes sense, children usually like outside in any conditions..
