It can be hard. My boys are 20 months apart. About 3 weeks I started sleep training, never letting the baby fuss for more than 5 minute but giving him the five to try to self sooth, even when he woke at night. (my doctor said babies no not need night feedings after the first 10 days of life and that they do it because we train them to). I had him sleeping from 8 until about 5 at one month, which helped a lot with my sanity! As for play time, I found something the baby loved (for him it was his swing) so that I could have one on one time with my toddler. The worst time was when I was breastfeeding. This was the only time my toddler showed true jealousy. I used both breast and bottle with both of my boys, so to help with the jealousy issue I would only breast feed when the toddler was not around, was napping, or was playing with daddy, and the other times I would use a bottle and let the toddler sit with us and help feed his brother.
Good news is, with 2 so close, they will have the same interest as they get older (same basic developmental stage), so they will play together and allow you a break! They will probably fight a lot, sometimes I feel more like a referee than a mom, but they will also keep each other entertained, allowing you more time to read, clean, bath, or whatever you enjoy. :)
