3am singing 5mo

[YourDaughterHasaTattoo]

For the last 3 nights DD has woken up at about 3am and sung on and off to herself for about an hour. She then drifts back off to sleep. It's driving DH and I mad as she's still in our room! Previously she's a good sleeper, goes to bed at about 7.30, dream feed at 10pm, then another at 5.30/6am. She has been unwell recently (just a cold) and the only way I could unblock her nose was to BF her so she's had more night feeds than usual. She has about 2.5 hrs of naps a day. Anyone else ever had a similar problem or any suggestions for how to get her to stop?!

No idea how to stop, but my DS when he was 5mths old used to wake up at 2am and was up until 4. I was just taking him to living room, he happily played on his playmat and I watched films. It lasted few weeks, stopped as unexpectedly as started. Good luck x

Thanks Luna, at least I get to stay in bed so far! Fingers crossed it doesn't last long
