People keep saying how Isaac acts older than he is, which is why we've started calling him baby, because I'm getting quite sad at all this older talk, he's still only a baby love my baby boy he absolutely loves standing up, and he can hold himself up (obviously we have our hands under his armpits for when he relaxes), and he can sit on our knee without a hand holding him up (again we always have our hand on at his back for when he slumps) - did your baby do these things at 11wks and before?
