Do you find that your little one gets upset if another sibling or child gets any attention from you? Do they get upset if you hold or pay any attention to another child? This can be very upsetting for both you and your child.
They are simply used to having you all to themselves, and they do not feel right that you are holding someone else.
You do not want to make your child insecure in any way, but you do need to wean them into sharing you with others.
They may be the same way with their toys.
If they are an only child, and have not been around other children, then it may be very strange and unusual to them when it comes to another child wanting to play with their toys.
You are going to have to intervene in this behavior, and gradually teach them how to share not only you, but also their toys with others.
It is not that they are greedy or unfriendly, it is only that this is a situation that they are unaccustomed to.
Here are a few things that you can try, to help them get used to sharing.
1) Get down on the floor with them, show your child and the other child how to each play with a toy.
Show them each, at the same time, how it works, and how they can play with it together.
If you make it fun for them, they will not pay so much attention to the fact that someone else is playing with it at the same time.
This may take a little while to get them to catch on, so be patient.
2) Take your child in your lap, and play with them, by rocking forward, and them pulling them back, like a game.
Do this for a couple of minutes, and then ask them if is alright if Sally, or Robert(whatever the other child's name is) can sit with them.
Then pick the other child up and let them sit on your other leg.
Before your child can begin to object, start rocking far forward, and pulling them both back, like a game.
They will be having so much fun with you playing with them, that they will not have time to be fussy about the fact that you are holding them and someone else.
These are just a couple of things that you can start to try and get your little one to become accustomed to sharing you and their toys with others.
It may take a little while for them to really warm up to it, but they will begin to learn and to understand that it is alright to share with others.
The younger they are when you do this, the easier it will be for you and them.
Do not force them, they will learn with patience.
