My lo is 7 mos old and my friend made me concerned about the fact that she cannot hold her own bottle or pick up a sippy cup with handles. She has only picked up the cup once that I have seen and that was by 1 handle in her walker and she managed to hold it up enough to get a few swallows out then it fell out of her hand. Should I be concerned that she hasn't gained that skill yet. She can crawl on all fours, sit up from crawling position turn around to look behind her while sitting, lean both ways, grab all foods given to her and put them in her mouth from her palm, she can lift herself up onto her knees and almost feet except for wobbly hips and not enough leg strength, she can also catch herself from falling on her face, and today she stopped herself from falling onto her back. She has a lot of skills that i have not seen in children her age before(not saying shes special, just saying i personally have not a met a 7 month old with those kinds of abilites only 9 months and older and I do understand that every baby is different) advice only please no criticism.
