Can I give him laxaday? If so, how much? If not, what can I do?

Hello, I have a 2 month old baby, 10 lbs He has been having hard stools since he was born, he has a lot of difficulty getting his stools out, I always have to help him, do the "bicycle", massage, give him water (recommendations from his doctor). He cries a lot when the time comes, he becomes red and pushes with all his strength to evacuate.
