My dd ( who is 2 and a half) has always been a "good" talker and has been able to communicate pretty clearly ( didn't walk until 19 months but that's another story). A week ago she suddenly developed a stammer ( intermittent) but is getting frustrated and upset when she can't get her words out: "Mummy, I can't remember it". Expecting dd2 any day now and I'm pretty sure this is related to changes at home ( although outwardly dd1 seems quite excited about new baby). We're not making a fuss about it and trying to reassure her when she gets upset. I guess if it's going to persist then there's nothing i can do about it , and if she's going to grow out of it there's still nothing I can do about it, but would be interested to know if anybody else has experienced this?
