14 week old suddenly feeding 3 hourly overnight

Be

The classic story - 3 month old was sleeping 5-9 hr stretches overnight and suddenly bam! Now 14 weeks and bub is waking up 6-7 times. I try and resettle with a dummy, in the cot and then in my arms but eventually need to feed. I’m so very tired (and so is bub!)

Someone please tell me that it ends!
