Hi twin mum.
Congrats on the twins!
when you say they are sicky, do you mean spill a bit or suffer from reflux, wind, gas or tummy issues?
Unfortunately i am not going to say what you want to hear
IMO they ae sleeping well for 10 week olds. It is very common, and normal for them to wake for feeds in the night. Some LOs do for a long time, esp if BF
What time do they go down for the night? Have you tried anything so far to assist with their discomfort after feeds?
