Nope, not a bit, the last few days the naps have extended to an hour, he has done this himself, for example yesterday he took an hour and half in morning, an hour for second nap, almost two hours for the next one and a 45 min cat nap, he did wake very early though, i think it might be a growth spurt, have increased his bottles to 8oz...(monster...) he slept from 8pm right through til 7am this morn....so its getting better......hoepfully. He is a big boy, much much bigger than ds #1, different build, and ds #1 was breast fed, so things a little different, but he is wonderful, just hope these extedning naps continue!!!!!!!
