My daughter is 15 weeks old and at our last peds appointment the dr noticed the back of her head was a touch flat. We have been so dilgent with tummy time (as much as we can), sitting her upright and off her head while holding her, and rotating her head while she sleeps. I'm not sure why she has the flat spot but it feels like it's basically on her fontanel. I'm afraid when we go back to the dr for her 4 month check up the dr will say something again 😣 I hate feeling like the dr is lecturing me.
