But, good to know that it may not cause blowouts. However, I still don't think it was appropriate to send him to daycare with it 
Dcm had several days where she could have given it to him at home, but gave it to him the one day he comes to daycare.
I want to say again that you did the right thing by dumping.
When I gave DD miralax it was at last resort and she was always in discomfort and cranky.
