Congratulations on your beautiful litter of 5! I just came for a thread looking at pics of 3 wk. old babies......my how quickly they grow! And daytime whelpings are great! I've only had one litter (so far) and it happened first thing in the morning; she woke us up to let us know it was time(so it seems). So I have yet to experiance a "long night".
Anyway, keep those pictures coming and hugs to you and your new fur-family members.
