Lip quivering in 4 mo

[CoalCraft]

Would this worry you? I went to GP about it a while ago and was basically politely accused of having PFB syndrome, but she was only about 1 month then. Internet gives mixed messages.

It's not super frequent. Tends to happen when she's a bit wound up but not crying.

Could it be related to tiredness? Or being a bit chilly? It wouldn't give me too much of a worry personally, but obv hard to say when every baby is so different. Maybe just keep an eye, and any changes to feeding/nappies then go back to the GP xx

Some babies just to it when upset - nothing to worry about x
