Two under two is not easy - but it gets easier. My first was 9 months when we conceived our second, and there are definitely pros and cons. They play together really well, best of friends, a year apart school wise. And you still have some time to work on the sleep. #1 started walking the day before #2 was born...so you still have a bit of time if you have a late bloomer with some things. I also know if people who have had trouble with their #1 children and worried about #2, but the #2 has been a piece of cake so it wasn't as bad as they'd feared.

I won't tell you it's easy - it's intense. A bit like doing an intensive course, rather than taking the traditional year/semester. It's full on for awhile, but the tricky (high maintenance baby) part is all done with all in one hit.
The important thing is to get some good support around you so you can lift your head to breathe regularly and also connect with your partner. That's really vital.

Another thought - a backyard might make a huge difference - we moved after #2 was born, from no backyard to a decent sized one, with a park around the corner and oh my, it's good. If they're crabby, high-strung, go go go, tired but won't rest, noisy, cheeky - send them outside. I can't believe how I survived without a yard. I can't believe the boys did. Find a good yard (maybe with an undercover area so outside's an option even when it rains), and somewhere for a chair/swing for you and baby - your days are sorted. xo
