My 3 week old usually doesnt sleep much during the day and at night would wake up like every 3 to 4 hours to eat. All of a sudden yesterday she took a nap at 2:30pm and even though i woke her up at 5pm to feed her, she went right back to sleep and the next time i tried to wake her up like at 8:30 she wouldnt. I kept moving her and nothing. She continued sleeping and eventually i fell asleep and woke up at 2:30 am this morning and she was still sleeping and so i tried waking her up and she wouldnt, i did manage to feed her a little while she was sleeping and so shes been like this since yesterday a non-stop sleeping. Is something wrong? Please help me. Shes just been sleeping non stop since yesterday afternoon and doesnt want to wake up to eat.
