Help a first time mom

Ashley

my 7 week old baby is feeding constantly and seems to have struggles pooping. i am exclusively breastfeeding and am at a loss. i know that babies have to start using their muscles to poop at 6 weeks and so far i know a way to help him and he will sleep for 7 hours at night but it’s a struggle during the day. he fights naps and then he gets overtired. any advice would be appreciated.
