My 10 mth old was a fantastic sleeper up untill a few months ago. but it's lately i am absolutely exhausted. he just got 2 teeth a few weeks ago and is now waking at least once during the night about 2 am then again at 5-6am. last night was 12am also. it's really exhausting with a full time job and doing this on my own with my partner away and i was hoping he would be sleeping by now. i have been giving him about 100ml of a bottle and he falls back asleep. but i read that a lot of people try crying it out. should i be CIO at his age. and if i do will it lessen every night till he sleeps through? or have i accepted it's just a phase and he'll get there one day

any advice is appreciated..cheers
