My 12 month old was 7 weeks premature and spent a month in the nicu now she is active so sweet and walks unassisted , eats solids , but she doesn't point she will just get what she wants to play with or cries if it's out of reach and she reaches out for hugs and to be lifted but doesn't stack blocks or point but she knows how to pick up with index finger and thumb and they said it's suppose to be developed at this stage ... should I be worried?
