my baby is 2 month old. durimg day time she is sleeping in craddle. but after 9pm to nearly 3am, she wants to sleep on my lap or shoulder. if i put her in craddle, once she went into deep sleep, 5 mins after transferring, she is waking up. if she is sleeping on my hand then she wont wake up. recently she had cold, so past few weeks she had nose congestion, but now congestion improved a lot. even then she is not sleeping flat in the craddle. what could be the reason and when this will change?
