I have a DS who is just 9 mo old. He's always been physically strong and very interested in the world around him and needed a lot of stimulation/interaction. But...he's turned into a whinging monster and it's exhausting!! I think he's frustrated that he's not mobile. He's been on the verge of crawling for weeks but whines when he tries then cries hysterically when he fails. If I sit him up or pick him up it makes him worse. Distraction doesn't work either! The only thing that placates him is if I stand him against a sofa/activity table. He seems obsessed with standing but again can't get himself into that position. I then have to sit with him as he likes to experiment with taking his hands off and sometimes topples (more tears). Sigh...I'm sure this is a phase but please tell me it passes soon??!!
