My LO is 14 weeks and we have a vague routine but as I also have a 3 yr old this is prone to change!
Currently my LO has 180ml bottles but quite often only manages 120ml. On these occasions she'll want her next feed within 3 hours. This often throws the day as her routine ends up roughly as follows:
7.45 awake
8.00 feed
11.00 feed
2.00 feed
5.00 feed
6.15 feed & bed
This then means that the 6.15 bedtime bottle is barely touched as she's not hungry. We tried a split bottle last night and gave her 90ml at 5 and then the rest at 6.15 but she didn't finish it.
Any advice would be appreciated!
