Give anything you like really
I based snacks on a couple of things
- giving an overall 'balance' of food groups across the day (so if she has yogurt and fruit for breakfast then perhaps something else for snack, yk, just think about the food groups)
- how hungry he was at that snack time (we had a long period of him needing a HUGE morning snack, almost lunch but at 10.30 - 11.00am so fruit just wouldn't have cut it)
- if I was at home or out and about (so how easy it was to transport and how much mess it made to eat)
Is your LO happy to eat family meals and finger foods now? If so then really anything, left over dinner form the night before... if not then perhaps this is a good time to focus on finger food?
Top snacks here were oaty chews (like flap jack made with oats and dried fruit but no honey or sugar or syrup), pancakes made with banana, grated pear or apple, mini muffins (sugar free) made with sweet potato or carrot, cheese scones, sugar free biscuits, crackers, crumpet or toast, fingers of naan bread. Oven baked wedges of potato or sweet potato, apple, pear, chunks of cheese. Most of our snacks I arranged around being able to take them out and about easily. And always some fruit.
As for how much, well I allowed him to self regulate so gave him as much as he wanted until he was full. I found this way that, yes, morning snack was huge, but he still ate his meals. Often LOs are less hungry at dinner time (evening meal) so it's ok to have a larger snack and less at dinner at this age...later on they can shift their appetite to more 'adult' times and eventually it is appropriate to limit snacks to ensure good meals are eaten with the family but your baby is still really young so follow her lead and you'll be fine. You only don't want the milk to drop completely but I'm sure it wont', you still have 3 bf per day and if she needs more milk she'll take it at those times.
hope this helps
