baby cant lift up head when doing pull to sit

Do more tummy time, need him to train their neck strength. And carry upright and support their neck. Can let baby tummy time on u 1st and slowly stand up while support his neck.

Baby should be able to lift his head when he's about four to six months. If you see that he's having great difficulty please do consult a pediatrician.

hi, so at how many months can he finally do it?? mine at 4 months now also cannoy lift up when pull up using hands.
