Why the fuck do people always jump on the RP without even reading what she says first on this board? I thought it was supposed to be for single parents, not for MRAs with an axe to grind? OP says that she offered more contact (an hour a week) and it's her ex who wants less frequent contact! So get your heads out of your misogynist arses and learn to read the post first, eh?
OP, it is true that more frequent contact is better for babies as they don't have long enough memories to cope with fortnightly contact like older kids who already know both parents can. With my ex, we did a few hours several times a week with me present at first due to BF of demand (as is recommended by the WHO and medical authorities, so stfu 'dads can do everything just as well' idiots- that is true for older children, not tiny babies- if dads want to do the best for their tiny babies, they stay with and support the mother up to at least 6 months instead of being violent twats). Now that she's a toddler (nearly two!) she is up to having overnights sometimes (he only wants one a week as he finds it hard to cope with more...- see, it's not always the RP who reduces contact, I'd love to have 2 or 3 nights of decent sleep a week!) and having full days with him. But then, he wasn't seriously violent, just a dickhead in other ways. As it is, it'd be ideal for him to have short, frequent contact, but really it's down to what you can cope with, as your mental health is the most important thing you need to manage for your baby's sake, and if he'd abuse you then of course you can't be around him alone.
As to whether it's appropriate to talk about 'offering' him contact- well, it was presumably his choice to be violent and thus not be in a normal relationship with his child (in fact, if he's not been around thus far, it really isn't 'his' child, any more than babies are the children of birth parents after they're adopted, ffs- he's not a father if he's not acted fatherly!) However, maybe if you say 'suggested' instead of 'offered', some of these politically motivated tossers will stop bullying you...
