LO in the last 4 days has had awful sleep patterns. He use to STTN but now is waking up between 9-10pm crying and 430am-530am. He also has a cold and/or teething. Bedtime is 630pm and he used to sleep all the way until 630am-7am. Naps use to be 1.5-2.5 hours now 45mins. I don’t know what to do. I went in last night and patted him but now it’s like he wants that every night. Suggestions? TIA
