What is a strong persuasive technique to let them wash their faces and
Sorry, but I don't think there is some magic technique to get them to wash their faces. However, if you try a few things, I am sure you will find a way.
- Just like with adults, many problems can be solved by talking to each other :-). Explain why washing is important, and ask why they do not like it; they should be old enough to explain if there is something concrete bothering them.
- If there is a concrete problem, try addressing it with them. For example, some children do not like getting water into the eyes during shampooing. I found that giving the child a cloth to cover the eyes helps - both because it keeps out water, and because it gives the child something to do to be in control.
- If they just don't like being washed, try making it a game, or distracting them. My daughter does not particularly like having her teeth brushed, but enjoys it if I sing her a song about fighting off teeth monsters while brushing. Different things will work for each child; try them.
- Try to involve them - children (like all humans) like to be in control. Let them squeeze the shampoo bottle, let them open the tap, etc. Maybe they'll even end up washing themselves :-).
- Finally, if everything fails, or you must hurry, just tell them firmly that now it is time to wash. If needs be, hold them gently but firmly and get over with it quickly. If you try the steps above, this should rarely be necessary. After you are done, praise them for having cooperated if they did not fight you. If they did, explain that you had to do this because being clean is important.
And they both do not like combing.
Everything above applies here as well.
Additionally, one concrete problem: Most children with long hair do not like combing because their hair knots easily (being very thin), and combing knotted hair is quite uncomfortable.
There are special brushes to untangle knotted hair - they have bristles of varying lenght, so they gently untangle. Look/ask for a detangling hairbrush or no-cry hairbrush (they exist for adults, too) - that worked wonders for my daughter. Plus, there are children's brushes with nice colors and stars or unicorns on them - your daughters may even insist on using them...
