getting my son to nap

Vanessa

help i have trouble getting my son to nap, he looks like he is sleppy but wont take a nap if i put him down, he is 9 months, he starts to crawl and eventually he will cry, the only way i can is to use tha infant seat in the stoller and walk around the house, now its been very hot and i guees the seat is too warm he looks exhausted but won't take a nap any other way, any tips?
