Slow down overactive let down?

Is there anything I can do to slow down overactive/strong let down? Baby is 4 weeks old. Luckily my baby has been a trooper and still latches, but initially was refusing to latch when the strong let down started. I have read that a strong let down regulates after 8 weeks and it usually happens when your milk supply is establishing. I just feel bad for baby and wish there was something I could do to slow down the flow. Lactation consultant said to pump for 1 minute to reduce the amount when baby breastfeeds, but I notice the strong let down lasts much longer than 1 minute pumping so it hasn't helped much. I really hope the milk flow regulates in 8 weeks.
