S.M.
Mine are 15 months apart. When my son was 3 months and daughter 18 months, I did a lot of things outside and shopping with them. I brought snacks, sometimes packed a lunch or we had lunch out. Mainly, with my double stroller that I had, when the little one was still in the carseat, he would nap in that in the stroller and my daughter would stay awake a lot longer, but the fresh air always tired her out. I'd take the time when I was out and they were both napping in the stroller (I'd recline her and give her a blanket) to head to the book store, coffee shop, or just walk more. I think it's a good idea to make your self do it so that they get used to being out and no how to act when you are out and you will get used to it so quickly. It gets so much easier so quickly. When your baby is old enough to start playing, you'll have two little playmates. It's only tough with having them so close together right at the beginning, but gets better and you'll be able to start playdates. I think playdates where you meet somewhere is hard at this age but gets easier when your younger baby is mobile. Also, playdates either at your house or someone elses house work, but not during either's naptime. Hang in there!!!
