well both of mine were like this and had to build up to a nanny over a few days, just being in the house in and around us. what were you planning to happen at your wedding? was your mum or another friedn going to look after him? I would start now on familiarising them with that person asap, as you want them to be there- just being close to them with you in the vicinity. so they know you are ok with it and ar close at hand. i think if they can see you that is better than being in a different room. but you might have to put some serious groudn work in urgetnly to avoid tears on the day. I thought all children were like this - but boys might be worse- anyway they do grow out of it- but i could never leave mine in creches and had to build up a strong relationship with a friend at church to take turns at the church creche. never managed ikea/ othe shop creches.
