DD 6months keeps tilting her head to the left, is this normal?

[Longo]

My very strong and advance (HV's words!) 6 month old has suddenly started to tilt her head to the left side and leaving it there! Is this normal? Probably being a bit crazy but hey!!

My Ds 2.7 used to do this as baby, he used to lay in the baby bouncer with his head practically on his shoulder. He is absolutely perfect now, no problems whatsoever! I hope this puts your mind at ease

Thanks roulade, feels lots better now!
