mercsboy:dun need worry la,zonghan went through similar case as kyler,i thought it was dawn cos usually he sleep through but recently he will wake up after 3 hours.i suspected it is due to his teething plus he is not feeling well so he gets cranky and cant really sleep.after about 1 week,he is much better and can sleep longer now.u can try carrying him upright and walking around the house,usually when i do this,zonghan will stop crying.apply some teething gel before he sleep also..think its really painful cos when i applied the gel for him,he will bite my finger and can see that he actually find a lot of relieft through the biting so sometimes i just use my finger as a teether.
