not crawling and not sleeping well at night

if the baby's stomach is not full then baby won't sleep.. make sure u feed her as her needs n give milk too

you can start cow's milk if the baby is 8 months I give to my 8 months old daughter. . starting mix half water n half milk slowly slowly add lesser quantity water n layer give cow's milk withoit addong any water... cow's milk is next to mother's milk as well

It's very much normal, every baby is different so she will achieve her milestones sooner or later. Even my baby has achieved some of his milestones bit late. Regarding sleep irregularity: 1. Baby may be colic. 2. Not fed properly (don't give cow's milk baby may suffer infections ) 3. Room temperature it should neither be too cold or hot.

Hi, every child has different development stages. So don't bother. Regarding sleeping, your baby might be teething, due to that she may not sleep nicely. If you also feel she is hungry then you increase bit of qty of her Daily food. Hoping you have started semi solid for her. If still this continues then better consult pedc. My pedc has give one gel when my son was going through same stage.
