Sounds pretty typical, the father making great efforts to satisfy the court that he is able and has the means to accommodate a young child for staying visits.Fathers who've expressed little interest always go over the top when they finally get around to showing some.New everything suddenly appears. That's what's happening here, I bet.
If he thinks he's going to get a custody order he's living in a dream world. It's never going to happen and he'll be told as much by any lawyer he asks, and almost certainly by any father who's been in his situation. Stop making worries for yourself! :)
The court always favours the mother of any young child. You wouldn't believe how poor a mother you'd have to be to lose custody. Even if you were a drug addict the court would try to leave the child with you as the first option, with help and support, but that's academic here. It's only when the mother so utterly incapable that the child is in some real danger of neglect that it will not leave the child with the mother. It certainly isn't impressed by differences in material possessions or size of home, even if the father's offering a gold plated buggy, a mansion and a live-in Norland 'nanny'!
