Hi AlsOne,
no advice, just letting you know you are not alone. DS started taking 45-minute naps at about 9 weeks (after one beautiful week of perfect EASY!! ONE!) and hasn't straightened out yet. I usually start the weeks optimistically and by Thursday or Friday spend the entire day crying right alongside him and trying not to toss him out the window or just leave him in his crib with the monitor off. I have also tried everything; W2S, shh-pat, extending A time, making it shorter, even AP on purpose. He is gradually getting immune to all the "cheats" like swing, car, stroller, bouncyseat, so i can't even guarantee myself a decent stretch of time to iron or nap that way anymore. I think some babies are just wired that way, and on my part I know it's not him that needs the help, but my expectations need adjusting. Call a friend in once or twice a week so you get a break and some sleep (the best thing I have done for myself is swallow my pride and ask for help!), and HANG IN THERE!! I know it's horrible; I'm living it now too. I'm wondering how I'm ever going to have the energy for LO#2, if I even want one. As my mom tells me when I call in tears, "No one stays awake for 18 years; it has to get better!"
