Not sure if anyone on here is pregnant or expecting fathers or someone you know who is pregnant, you can obtain free nhs prescriptions (£7.10 normally) for 12 months after the birth of your baby. Also, I think you receive free dental treatment for 6 months - 3 prior and 3 months after.
Further details - follow the link.
PS. Don't forget to sign up for Boots Parent Club - you receive half-price on certain baby products http://www.bootsparentingclub.com/index.php
