Hi, being nosey on this thread as I'm a nanny to twin boys just turned two.
When I first started out with them a few months ago, they were 18 months they were like yours. Hadn't walked about used buggy all the time. No,soft play, no groups etc etc.
Was a bit wary of taking them out on my own at first and as they bith have such different personalities it aloud me to help settle the unsettled twin, while the other was confident enough to go off on his own.
Soft plays were a nightmare to start. They didn't know what to do, were unsure, and dint like the texture if the mats etc. by about the 5th visit they were confident and started toddling off. By week 10 they were off in the big area on their own and would come back every now and then or I'd check.
Toddler groups I started off with my friend again, they were a little wary to begin with learning the routine, play snack, tidy, song time etc, by the 2nd visit they were a lot more confident.
Parks, we went along with said friend let them walk, call them back, walk cal them back. They soon got the hang of it, if they didn't come back they wee sat back in pram then let back out etc etc. now can walk and come back (as much as a two year old toddler can haha!!)
I did all of the above during June, then by the summer holidays I had to then add the older brother and sister into the situation so met up,with said fr end and her 3 children and we got up to all sorts. Some places it was hard work but others I found having the older two there easier aswell because they just tagged (were dragged) along.
Now I'm confident enough on my own to take the twins out places during term time, then in the holidays I have all 4 Andre go off for days out on our own. We go everywhere hardly ever at home as they are in 3 days a week, I feel going ou places has bought them on so much with speech, being sociable which they were pretty bad at, as they were used to being with each other, ones boss the other submissive, well they soon learnt it doesn't work like that in the real world.
We go to soft play at least twice a week, song club, library, toddler group, swimming, walks, cafe, meals, shopping, semsory group, parks, play dates.
Can't wait yo go back after Christmas to get started on crafts, messy play, sensory things, being more grown up walking about :)
