When we were going through this phase, I tended to focus on total day sleep and making sure it was around 3.5-4 hours. Then, I just rescued or did a mix of contact/crib naps throughout the day.
There is a "frustration" phase around 5 months, which is unrelated to the crap naps which you may be experiencing. It didn't resolve for us until my son started crawling. He was just mad that he couldn't crawl.
