Sleep and breastfeeding

I’m exclusively breastfeeding and my LO has started to sleep between 7 and 8.5 hours at night from only doing 2-3. Up till 7.5 weeks old, now 8 weeks. This has meant my supply is crazy on a morning and I’ve leaked all over the bed (thank goodness for a waterproof sheet!). He then tends to sleep for another 2-3 hours before we get up.

This is since I’ve been putting him to bed at 10pm after a long feed and I follow him after 20-30minutes when he is asleep.

Any ideas if I will ever not leak all over the bed and my bra?
