You can always enroll her in some toddler classes... ie: Gymboree etc.
To me, actually, your girl seems to have a real full day... already. It is just that she has a routine, and perhaps she/you are bored of that. Its okay. That is life... and actually a child can 'learn' from that... that not every second is entertainment 'for' them. That sometimes quiet time and just doing nothing is valuable too. And actually, they (the child experts) say that many children are actually "over-scheduled" and they haven't learned to entertain themselves or to have self-reliance or self-directed/motivated moments. Kids learns TONS from just being non-busy too.
My daughter and I would love to just lay out in our yard, on a picnic blanket, looking up at the sky and talking about anything... mainly my prodding her imagination... about what she hears or sees or HOW she can describe it. We made a game of it. And sometimes, we would just read and lay out... or I would just read and 'let' her just be in her own thoughts... and if she had a question she could ask me anything. She told me she actually "liked" doing nothing sometimes and hearing her own voice in her head (ie: in her thoughts). She said it felt 'less crowded' and nice and quiet... to be just hanging out without "having to" go anywhere or do anything. It was actually our "special" time together and our quality time. I now do that with my son too.
For me, I like that my kids actually have nothing to do sometimes.. and then I challenge them to think of something on their own and then they do... often constructing things with whatever we have in our living room... Or making up their own games and then they 'teach' me their games and we all play together.
try playing Simon Says... or charades with your girl. Even at this age, you can adjust it to their age level and its tons of fun.
Sometimes my girl will tell me its "boring" and I tell her "yes, sometimes it is... but its how you look at it...that's life. and then I tell her "I bet you can be resourceful...." and then her wheels turn and I see her "invent" new games and crafts ideas and then she is SO proud of herself. I sometimes "on purpose" do NOT entertain the kids... just to see what they can do on their own or come up with... or to help their ability to think on their feet.... and be resourceful. And it gives them good thinking processes...
Just my thoughts. But yes, I know some days are just that "what now?" and I get that way too. But I have realized, now with 2 kids, that I don't "have to" entertain their every second just to be a "fun" or "good" Mom. Sometimes not being busy is just so great too.
All the best,
