Hiya,
How many bottles is your bub having during the day & how much at each feed?
Did you drop bottles for the solids?
I'd been advised to give milk feeds before solids until bubs at least 8mths old & offer solids 30-60min later.
Not sure how much your routine has changed since your son has started solids?
Here's what I do for my 5mth old but only a few changes would be made for 7mths.
6.30am breastfeed
7.30am breakfast/solids
8.30am-ish after 2hr-2hr15m from waking- nap for 1-1.5hrs, awake around 9.30-10am
10.30am breastfeed
11.30am lunch/solids
12-12.30 after 2hr15m-2hr30min nap (1.5-2.5hrs)
2-2.30am breastfeed
4pm bottle 110ml top up
4.30 catnap (however you might find you 7mth old wont be having this now?)
5pm bubs woken
5.15pm dinner/solids
6pm bath etc
6.30 bottle 220-300mls we offer as much as he wants.
isnt fed for 12hrs.
BUT he was waking in the night for a feed like your son, so we decided to wean him from them meaning he would take more during the day. We also stretched out his milk feeds to 3.5-4hrly to encourage better feeds. so the first night we offered 100ml bottle at each waking, he was taking better feeds during the day esp that 1st one. after 2 nights he wasnt even finishing his night feeds so switched to offering 100ml of water, he would fuss a bit more going down but would go back to sleep, again he was taking in better feeds in the day, after 2nights he wasnt interested in the water so went to doing controlled crying whenever he woke, took 2 nights. then sleeping through to 4.30-5am but will chat away & go back to sleep until 6-6.30am.
Not sure if this will help??
