16mo DD is just about to take her first steps on her own, which is lovely, but the past week has been waking for 2-3 hours during the night. She is really difficult to settle, I try to co sleep but she just rolls around the bed so it isn't relaxing as I am constantly watching to make sure she doesn't fall. Last night was the worst - into bed at 7, up at 10 briefly then awake from 12- 3am..... And she just either point blank refused boob or tried to latch on and then started crying. Eventually she would take the right side but still today is refusing the left - bit worried I will end up lop sided! Is this all linked? I know the walking and waking probably are but not sure about the feeding. These days she doesn't bother with boob really during the day except for nap time and bed time and sometimes if I've been at work all day then come home. She still feeds at night maybe twice. But the refusal is out of character - any thoughts?
