I think it can be normal, specially if they are not pregnant or are childless.
You are worried about your baby and your planning goes around your baby all the time. If your friends are not in the same situation, it's quite normal they drift from you a bit.
ive hardly seen my bff since i got pregnant, which is a shame cause shes normally an awesome person, but i think she's slightly jealous (not in a nasty way) cause she has no children xx
I have the same Hun my friend only ever texts me when she wants a babysitter coz she wants to go out and get drunk! Never just texts to see how I am! She's Off the baby cuddling list!! I would never single a friend out because their pregnant! It saddens me to think I actually would rather have no friends than friends that don't go out their way to see if ur ok! U have us baby and bump
