ds is 3.5 and has some sensory issues so night time is always a battle for him. dd is 16 months and for the most part has always been a good sleeper. (they do share a room) she recently got rotavirus that lasted for 3 weeks. before she got sick she would take a nap at 12:15-2/2:30 then got to bed at 6:30 and sleep till 7. when she got Rota most of her throwing up happened after she went to bed. i think she got used to waking up in the middle of the night. she has been better for 2 weeks now and every day/night we have had the same sleeping problems. she still takes her 12:15-2/2:30 nap but at bed she fights it for at least an hour. then every night she wakes up at 3am. she use to co-sleep with us but wont do that anymore and only wants to be rocked and eat pretzles. any ideas or natural "remidies" to help her fall and stay asleep?
