You know you are a twin parent when...

One of the best feelings in the world its being and becoming a parent but when you become a parent of twins or more there are some things that only twin parents will relate to for example

You know you are a twin parent when.... people say to you having two children with a small age gap is the same as having twins and it really isn't having to babies to change, wind and feed at the same time are not the same as having two children a year apart in age gap.

Twin Parents should be able to relate!

1.  You are so tired you know you have fed one twin but can't remember which one it was.
2.  You are so tired you just lost count of how many scoops of milk you put in the bottle and have to empty it all over again.
3. You become an expert at carrying two babies around in your arms or on your hip.
4. You would be a millionaire if you got a pound for everytime someone told you-you had got your hands full. 
5.  Perfect strangers think it's acceptable to ask if you have had fertility treatments.
6. You buy a bigger car and are actually ok with it.
7. You resign yourself to the fact you won't have a tidy house again for a very long time.
8. When someone tells you that they know EXACTLY how you feel having twins because their kids are 18 months apart and it was just like having twins and you have to stop yourself from jumping down their throat and telling them how wrong they really are!
9. You know what the word “singleton” means.
10. If you have twins that are a boy and girl you are fed up with trying to explain as to why they are not identical.
11. You know that feeling when they are both looking adorable then one of them throws up on themselves.
12. You don't think it is acceptable to just send one card or one present between them.
13. You have learnt how not to make eye contact with people when you go out so you don't get stopped every five seconds.
14. You are still thinking about whether you sing happy birthday once on there birthday or once for each child.  
15. You seem to get an instinct for wanting to buy everything in twos.

What would you add to the list because I am sure there are some things I have missed!? 

looking forward to hearing your thoughts.
