Is it normal for a 10months baby to drink only 100ml every 3hrs? Is it too little? Solids will be 2-3 times and each time 2-3 table spoon.

my girl also drinks so little. when I am at work.. she only drinks 300ml throughout the whole day and only 1x of puree.. however she dun poo everyday. like once every 4 days? is it of a concern?
