I have finally bitten the bullet and booked swimming for my 21 month old. A bit scared TBH - so talk to me about practicalities and tips. He is boisterous - does holding hands occasionally - when is it best o put swim nappies on there - what is the best method for getting oneself and toddler dry or into swim gear! We live 5 mins from the pool so happy to go with my suit on underneath etc
