Pulling to stand

Emilia started to pull to stand few weeks ago. First she did this while she was in the bath tub. She would hold onto the tub and stand up, and next she did it in the crib. I hear and see a lot of babies at this stage do actually stand up unsupported and cruise alone holding onto furniture.  Her gross motor skills may be a bit delayed but I am glad she is making progress each day and week. She also now kneels down, unsupported. She can take several steps forward as I hold her hands and ask her to walk too. In about a week, we have a follow up appointment with the NICU. I am already anxious about what they are going to say about her progress. Every time I feel like she's on track, the NICU follow-up seems to throw us back.
