Thank you.@jessicagarmal, .I though that so .there were 1 month earlier. and still a month behind .

my sister and i didn't.. we were premies.. and i think a lot of twins are.. they just worked with us.. like extra tummy time.. used blues to support our lunbar system.. and eventually were did probably closer to 7-9 months.... we didn't walk to maybe 16-18 months.... were were small for our age to... we were fine in their long run sometimes it takes twins longer to hit those first milestones then they take off with development...

@jessicagarmal,

maybe. .

is normal thst they don't seat by themselves at 28 weeks old

i am a twin if that helps
