as long as all her needs are met then just leave her, don't stop or she'll never change. i don't agree with the CIO method but you have to be able to do things. just leave her be and don't stop. i know it is soooo hard but it doesn't help to stop, it just prolongs it for her. play the music loud for her, give her toys, and keep on rolling. the safest position for her is rear facing so leave it at that as long as you can.
for a cold and fever, use Tempra. i use it for my 8 month old (just once in a while). as for the congestion get a humidifier, my son has just got his first cold and I used a humidifier for a week and it helps, I also give him a bath before bed and that helps clear the nasal passage.
one more thing, my son is 8 months and 22lbs, 30inches tall. i
still have him rear facing even though i could probably put him forward. his seat is good for up to 30lbs and 32inches. i know he is safest this way.
