Oh Bright this is awful this is happening to you, but I'm so thrilled you are seeing him tomorrow. As I said to you earlier in the posts, I've had some experience of SS, as have other ladies.
They are human. They get things wrong. Most of the time But as mothers, we see them as the law, we're frightened to rock the boat in case they swoop in and remove all our kids etc.
They really can't do that without a judge granting them permission, and no judge in the country would do that here, unless there's a lot more to the story than what you have told us (it doesn't sound like there is)....but I wouldn't wait for meetings on friday with a solicitor, I'd be on the phone now demanding someone act on my behalf, just in case they are stalling you while trying to go to court to get anything in place that would mean you'd have to jump through a lot more hoops before he's home. They have been known to be sneaky that way, and at least with a solicitor on the case they'd be on top of that.
Withdraw consent to the section 20 immediately. You get yourself ready tonight with everything you need for your baby, and you go collect him tomorrow. You don't need permission - this is YOUR baby x
Please please try and take someone with you. This is an emergency. The harder you fight, the more kick ass assertive you are, the better!
We're all behind you! heck most of us would like to come to the SS office and stage a protest until he's in your arms I expect!! x
