They don't call them the 'terrible twos' for no reason. Your toddler daughter is growing up, becoming a person and not a baby with a definite personality, wants and needs and now she can express herself a little most distinctly. You on the other hand are going through sleep deprivation for the 2nd time, juggling a toddler and a newborn. Your life is on overload. A two and half hour nap in the afternoon is a long nap for a toddler. She doesn't have the same sleep requirements that the baby does. She also wants some attention. She's accustom to being the princess and getting your undivided attention. So, when you have the baby napping, take one or two of those nap periods and have some Mom and daughter time. If you cut back on some of the nap, she may sleep a little later. Then you need to remember a toddler's body clock doesn't coincide with the clock on the wall. We just went thru a time change, from standard to daylight savings time. We sprang forward 1 hr. So waking up at 7 am today is like waking up at 6 am last month. Her 6 am wake-up is her routine, nothing new there. Let her enjoy that half hour or so with you and Dad, without you having to rush to the baby. You'll have a happier daughter, a less frustrating day, and you'll be laying the groundwork for a great relationship between your kids, a non-competitive one, where they each have their time with you and then the shared times as well.
