I don't have any advise. To be honest I know eventually my husband and his mom are going to want to take son to Florida and Disney since they have family there and it makes me so jealous! He will have these great memories with me excluded. I will be missing out and this wasn't my choice to divide the family up. And of course nervous for son to be away from me.
I just try to think that it will be a great experience for my son and that I get to do tons of fun stuff with him all the time. I try to think that there are so many worse things and that I am so lucky to have my son. I know how you feel though.
What is it specifically that upsets you? Do you have a say in this?
