Is baby eating enough? Formula and solid fed

Ash • Married 💍

So my little girl wakes around 8amish and has 5oz milk followed by porridge around 10am. She then has around 6oz about 12pm and a tin of baby food (pasta with cheese or fish and veggies etc) about 2pm. She then has a long nap and 4pmish she will have another 6oz milk followed by some fruit around 5.30ish. Some days she will have some rice pudding for dessert around 6.30pm depending on her mood. Then bath at 7.30 and 5oz at 8pm before bed. Is this enough? Shes always had trouble drinking lots of milk since birth its always been a hassle with colic and then reflux. I do think shes getting enough milk though as the tin says once baby is weaning she needs around 18-20 oz a day and she gets around 20-22. She likes foods but can sometimes get fussy if shes not in the mood or having a bad day.

I feel like i need to up her food solids intake. My mum however says i feed her too often and i need to let her stomach relax and digest before moving on to the next thing. Baby has always been in the 25th percentile in her weight since birth. Today i offered her an extra tin of solids at dinner time and she took it like she was starving. Other days she doesnt always even take the bare minimum. Just curious if people think this is too less or if i should carry on as is. Any advice welcome!!!
