That's fantastic that your Dr and MCHN weren't overly worried about it hun. Oscar had a flat head (side) which is barely noticeable now. I took Oscar to a chiro a few times and they found his back was out from his birth. It only took 3 sessions and he was much better and started sleeping on both sides of his head and also on the back of his head. I was still concerned when he was around 6-7 months so I got a referral from my GP and went to the Prosthetics Unit at the RCH in Melbourne where we saw some lovely people! They gave Oscar a score as to how bad his head was and he was below 5 (I think that's right) so they wouldn't fit him with a helmet unless he was a 6 (I think). If we had of taken him a month prior I am 100% sure they would have given him one as he was really bad. It's amazing how much and how quickly their skulls adapt. PLUS... if you really don't want him to have a helmet that is completely fine. It's nothing his hair won't cover in time. Plus, it also doesn't affect their development or their brains. It's more a cosmetic thing iykwim?!

If you want anymore info let me know hun and I'll try and help you out. Also google Plagiocephaly on the RCH website and that will give you some great info.
