Hi ladies. My son is 5.5 months old and he used to sleep about 9pm to 3am feed then back to sleep until my older kiddos got up for school. The past few weeks he has been getting up more frequently. The last 2 nights he slept from about 8 until midnight/1am then I pretty much cant put him down. He falls right to sleep as soon as I nurse him but if i take him off he wakes right up. I'm exhausted! I do notice a little bump on his lower gum so maybe he is comfort nursing because hes sore? Any advice?
