Hi, thx for the suggestion, i must admit i've tried to change his sleeping pattern multiply times with no result (tried to skip the nap so he goes to sleep at 9pm and he wakes up at 10.30 and keep awake till 2am - after the third attempt hubby just give up, says to let little one sleep at midnight).
As for the honey water, my mum suggested it, and i've talked to his pediatrician and as long as it is pure honey (without added sugar) it won't rot his teeth. I'd be careful with store bought honey though - many claims no added sugar, but we never know.
Since i've friend who make the honey herself, we feel safe to give it to him (she suggest we let the honey simmer for a while and use only the top clear part for the baby).
