I must admit that I have 3 major mental hurdles with Aran at the moment:
1. ditching the bottle at nap and bedtime (he uses a sippy cup all another times)
2. ditching the dummy (you are not alone Nadz

but Aran only uses it to sleep, so not sure how to proceed)
3. potty training
You know, I don't even take Aran to the shops etc anymore, unless DH or my mom are with me and there isn't any major important things to do, so if he's crabby we just pack up and go home.
We are having our 2nd baba in August (should be ….. interesting) as Aran is very used to having everyone's undivided attention all the time. So this should make for interesting times.
Oh Nadz, if Bella is using the dummy all the time, start by limiting it to her bed or cot. A friend of mine tied her LG's dummy to the bed so if she wanted to suck it she had to sit in bed - well, not so interesting after a while, so she would just leave it. As I said, Aran already only has it to dud, so not sure what the next step should be ??
