L.T.
Just like anything else there will be days when you are bored of the same routine and there will be days that you are so busy you won't believe how quickly the day has passed you by.
One thing would be to join a mom's group. That gives to access to playdates, help with babysitting, visitors to your home to break up the monotony (not sure sure I spelled that correctly). Maybe you could run errands together. I found it hard to run the quick errands, ones in which it took longer to get the kids ready and load them in and out of the car than to accomplish just the actual erreand. A friend and I used to carpool for errands. We would get our kids together in one of our cars. We would decide where we needed to go (post office, bank, dry cleaners, quick stop to the grocery store). Each of us would watch all the other kids while the other ran in to compelte the errand. In one hour we could complete so much.
Look for gear that will help you. If not a stroller how about the baby carriers you wear or a sit and stand stoller?
Plan your excursions a day ahead. Set a schedule. I use dto plan a detailed schedule (still do sometimes) that said what time to wake up, when to serve b'fast, when to dress the kids, etc. It really helped me stay on track. Pack the diaper bag and other necessities the night before.
Check around now for places that offer infant/toddler activities. Where I live free/low cost outtings in the winter include library programs, mom's groups, storytime at Pottery Barn Kids, indoor playground at the mall.
Buy a book that has a calendar of ideas for young kids. I used to have one made by Baby Eiinstein that had 365 activities. Even if I didn't follow the day's activity to the letter, I used it for inspiration.
Best wishes to you!
