My daughter is 5 months old. I know she isn't ready to wean yet. She has started waking through the night and seems very hungry. Do you think its time start with the solids ?

It could be sleep regression or growth spurt. If your baby's daytime didn't nap well, it might be a sleep regression. Try to avoid over-stimulation/over-tiredness during daytime and establish a scheduled naps for baby to see if it will improve. If daytime naps are well established already, it might be baby going through a growth spurt. You can offer more milk/breastfeed more often during daytime.
