GIT presentation of Intussusception, Pyloric stenosis and Hirschsprung's disease

What's the approx. time for the presentation of Intussusception, Pyloric stenosis and Hirschsprung's disease. I came across a lot of questions that talk about intestinal obstruction in newborn that don't give you the obvious hints (eg: projectile vomiting for pyloric stenosis) but just give you when the symptoms started in hours or days and then they will give you all 3 or 2 of these diseases in the options.

Pyloric stenosis occurs between 2-8 weeks. Any vomiting before 2 weeks is not Pyloric stenosis ( might be duodenal atresia)..

The peak incidence of Intussusception between 5-10 months of age..( colicky pain and vomiting .. Milk then bile!!.and red currant jelly stool
Hirschsprungs.. I dont know exactly but its typically occurs in neonate period with delayed meconium passage, bilious vomiting..( sigmoid commonest)..)
