We have an almost 4 month old baby. We've recently noticed that she will always turn her head to the same side (her left) when she falls asleep, is lying on her playmat etc. We've tried things like putting pictures in her pram on her right side or only putting toys on her right when she's lying down to encourage her to turn that way but she still always goes the other way, or contorts herself so she can see them without fully turning her head, or looks out of her peripheral vision! If I feed her lying down so she has to turn her head right, she will do it for as long as she's feeding and it doesn't seem to bother her, but then immediately turn her head the other way (sometimes quite violently!). She now has one cheek slightly larger than the other and we think it might be due to this.
Anyone experienced similar and what did you do? Various internet sites suggest tummy time will help but we already do quite a bit of this!
