Hi ! My baby is 3 and half months old now He doesn't have a proper head control yet , he is able to hold his head but when he turns its not stable ..it still dangles but not as fragile as before , also he tends to keep his head in tilt on right side while sleeping and most the time as well Is this something I should be worried about? Because many say by 3 months your baby should hold his head What should I expect ??? But my baby did roll over 2 days back
