Just to say I'm thinking of you too. Ive only just got past Lydia 6 month, and I can understand your feelings. We're hoping to ttc in september, if it works it will mean I'm pregnant when Lydia's first birthday arrives, such a mix of emotions isnt it.
Thinking of you and little Zachary, I hope you find a lovely way to celebrate his Birthday.
Mummy to little Lydia, born 16th December 03. Passed away 21st Dec 03 in her parents arms. Forever missed.
