DS is 19mo and cutting his last four molars (early I know!) If I give him Nurofen at bedtime he will sleep for 4hrs+ before first wake up. If I don't then he will wake every 1.5hrs through the night. I'm really worried about doing this every bedtime though as obviously it's a medicine and these molars are going to take ages (his first set took about 4 months from beginning to end). But the alternative is a really crappy night for everyone. WWYD?
