If the Orders/PP are about to be sent to the H, then maybe you could work some changes to the PP to address the issues and proposals you're raising in your latest post, and then explain these issues in the covering letter from the L.
That way, it alleviates you of having to broach them direct with the H. Don't torture yourself having to worry about raising these things direct with the H.
Please, please get some detailed advice about the prospects of you securing sole parental responsibility. Putting it forward now may be the 'offer him an out' Hawho suggests.
Get the daycare to inform you direct by email so as to avoid not being passed on from H or Chinese whispers.
Instead of your place for contact, could your parents or paternal grandparents place be an option, notwithstanding this will be a change in routine?
If it were me, I'd not only want an address, but also who else resides there and suitability of the residence to your son (ie amenities, condition etc). What if H is couch surfing or living with random tenants or new found xbox buddies and then decides to move? Be cautious in agreeing to upon address being provided S can stay there automatically. I'd also be proposing that when S is in H's care, H doesnt delegate care to anyone except family etc.
With breakfast (playing devil's advocate here) H could be bringing something in tupperware and taking it back, or actually cleaning up after himself. Do you honestly think H is that dilatory that he wouldnt feed his baby son breakfast? If so (actually based on what you've said I wouldnt be surprised), just make up a little breakfast pack H can just feed him with.
Overall, you're right in saying now's the time to propose and incorporate these changes, before the documents go out to H.
Cheers, Ds
