my son is 7.5 months old. ive recently started just offering water through the night instead of milk which is going ok...however he wakes up at 5.30am and turns his nose up completely at water and crys until i get him up. i have tried the cio method but as its an awkward time in the morning...it wakes my 4yr old up and its not fair on her so i dont really want to do it. has anyone any tips or advice please? i just need him to go to 6.30am as thats when my other child wakes up anyway
