My 8mo old breastfed baby has suddenly started sleeping way more than usual. Usually have 2-3 night wakings (on a good night) and takes two 2hr naps a day usually. He had to be woken up from both naps yesterday at 2hrs, last night he went to bed at 8:00 woke up once at 2:30 and went back to sleep until 6:30. He is still currently taking his morning nap and it already over two hours. Just wondering if this is normal??? Any reason I should be worried?? First time mom obviously 😬😬
