My baby is 5 days old. he prefer to drink from my right breast than left. he also drink only 10 minutes and then sleep for 4-5 hours. is it normal?

It happens: Some babies prefer one side to the other.It can be the comfort they feel while you hold them in that position.Sometimes altering your hold and always starting on the less preferred side will improve the situation.The breast yields 85% within 5 & almost all within 10min. If the breast is producing enough to grow baby will sleep well after a feed.
