Hi
Phoebe was only on 2 bottles at this age, about 12oz in formula and rest by milk included in cooking,yoghurts, dairy products.
Your LO in heading in right direction as solids will soon become main food source.
Phoebe has always been on the lower milk intake threshold, if she wants morethan she'll take it.
They are all different and books give us guidelines so don't panic.
If LO not taking milk, give yoghurt, cheese, homemade fruit smoothie yummy and so much nicer than plain milk!!!!
Good luck,
DEbs
