Sorry Ams25 that post may not have come out as supportive as it did it in my head, I genuinely feel for you and can't imagine dealing with DD's poor sleep with a second child as well. You should do what you feel comfortable with and what gets you through. x
Curious to see if other parents with poor sleepers identify with the Dr Sears "high need baby" theory. I try and remind myself of the plus points of having a high need baby whenever I'm feeling really down.
"THE CHANGING PERSONALITY PROFILE OF THE HIGH NEED CHILD
The words you use to describe your high-need child will change over the years, as the traits that so exhausted you during infancy are channeled into qualities that will make your child an interesting, dynamic adult. Try to think of your child's personality in a positive light and look ahead. Labels that seem like negatives will be positive traits in your child's future personality.
INFANT
alert, intense, draining, demanding, cries impressively, loud, unconsolable, supersensitive, high-touch
TODDLER-CHILD
busy, high-strung, exhausting, spunky, energetic, stubborn, impatient, strong-willed, obstinate, discerning, challenging, expressive, tantrum-prone, interesting, tender, huggable
TEEN-ADULT
enthusiastic, deep, passionate, resourceful, dominating, opinionated, determined, insightful, fair, sociable, compassionate, empathetic, caring, affectionate
Got to go wake up DD from her nap now, crazy little thing woke up for the day at 5am then went back to sleep at 7:15....at least I got to have a shower uninterrupted.
