Ainsley,
NN wont have no sense of security lah. U did not left her alone to cry what, u were beside her. She crying can't she dunno how to fall asleep, she thinking "mommy i can't sleep! i will need mommy to comfort me!! why i cant sleep?"
We did not try the cry it out method, we did not left her alone. I carry her put her down, pat her, carry her, all the while im with her.
BTW dun be affected by what pple say. They are not the one that wakes up every hour. At the end of the day, u choose the way u wanna raise ur child, the way u are comfortable. I'v a gf who carry her son for 1hr or more, then only when son in deep sleep, she put him down and he sleep from 10plus to 5am. I wont want to carry yuyu for 1 hr plus, in future when she bigger, i doubt i got strength. But she ok with it, its the way she like it, i wont say its wrong. For example, if u are ok with nursing nn to sleep, i would think its ok too. The only problems i read, whatever the reason as long as its not the baby own ability to self-sooth, it will have issues like frequent waking up at night as the baby grows old and more active.
