Ai yi yi...planning for retirement

As we (me, a US citizen and my husband a French citizen, both working in the UK) are getting ready to have our first child, i've started to explore the whole college savings/retirement plan question for us as a family. I am hopeless at these sorts of things, and thought i was being very responsible by signing up for my employer's pension plan when i started a year ago. Now i'm worried this could be money i'll never see again, because it's such a small amount (less than £1500) in pension terms.
We plan to be in the UK for at least the next two years, but beyond that it's likely we'll move back to France or the US to be near family. Only thing is we have no idea which it will be or when, since much of that will depend on jobs and other circumstances. My husband has also been contributing to a pension here in he UK.
I realize we probably will need the advice of an ifa at some point, but was just wondering how others in a similar situation might be handling this issue. Should i try to get out of my pension contributions as soon as possible? Should we be putting our retirement savings instead into a personal account? Is there any solution that offers flexibility for families like ours? Thanks for insight!

As a US citizen the IRS makes it difficult to invest outside the US. However, a UK employer sponsored retirement plan is a good way to do it as they are covered in the US/UK tax treaty. Remember that you have to declare any employer contributions as income on your US tax return or use the treaty to exclude them.

Unfortunately other investment options are complicated for US citizens. You want to avoid UK mutual funds and stocks and shares ISAs as they fall under the IRS PFIC rules.
