Spoke to hv today as noticed when stroking my 15 week old little boys head he has like a flatness on the left side almost like a dink.Im worried sick that i have caused this as he has his play gym and loves to kick about on that and has now started to sleep through the night on his back,other than that i try to keep him off his back as much as possible.Which was the hv advice which i cant understand as i do do that Anyone else experienced this am i being over anxious as i am now sick with worry
