I found it pretty hard for the first few months to be honest. I was lucky enough to have DH home for 8 weeks after I had DD.

She rarely slept at night. sleep 4-5 hour stretches during the day though..

It did get better and even though I now have 3 in school I still find when all 4 home tiring and very loud.. I avoid shopping on my own if I have more then 1 child. But seeing the ages of your kidlets. Shop online or wait till your DH is home..

But I do promise getting out and about with 4 does get easier. and I did it and I didn't have my license either until last year.
