I fought it for a while, but eventually gave up. If dd was happy, or relatively so, I just went with it. And with two under 2 you definitely have your hands full! I stressed for at least a month over her 45 min naps and ended up making myself nutso. I was a basket case - crying ALL day, and I am not one prone to depression, and didn't seem to have any problems with ppd till I started obsessing over her naps. Once I gave it up, we were all so much happier! If you have the time to fight it, it is a good fight to fight, but it just was wearing on my sanity too much. As soon as we moved to a 4 hr easy at 4mo, it all just clicked and she quit doing the 45min naps. Good luck!!
