You could try making some busy bags. These are fun little activities that fit in a ziploc bag. This website is a great resource: http://moneysavingmom.com/tag/busy-bag-ideas

We are out as much as possible usually, especially when the weather is in the 40s. That way, on really cold/rainy/snowy days, it's okay to stay in. We luckily have a community playroom in our building too. Aside from that, DD #1 (almost 4) goes to preschool three times a week and ballet once a week. I take the two to the library for storytime once a week too. Other than that, playdates. Sometimes on a day with nothing planned at all, just a walk is nice. Even my older DD finds grocery shopping and trips to the bank fun because I keep them short and try to get her involved as much as possible (putting things in grocery cart, giving debit card to cashier, etc). It's not easy juggling two out and about and solo, but it gets easier!

Edited to add: oh with nursing the little one while out, that can be tricky. I try to plan outings around feedings, but with how hungry they are in the beginning, it's almost impossible to avoid having to feed in public. I always bring my cover and have also learned a few times to nurse while she's in her carrier (Beco Gemini).

I just this saw this and remembered this thread. There are some good suggestions here!
