Hi, I'm sleep deprived and rambing, so please bear with me! DS2 is 4 months and was doing really well, more or less sleeping through at 2 months, a happy, smiling baby. 10 days ago I started back at work (evenings until midnight max) in a restaurant. We really need the extra money. DP looks after the children and puts them to bed. DS2 was EBF until about a week before I went back to work-I introduced a bottle of formula at bedtime which my DP gave him (can't express) and things seemed to be going fine, he drank at least some of it and slept ok as usual.
But since I have actually started work for real he refuses the bottle, or takes it a bit then looks at my DP and bursts into tears, then refuses it. It's breaking my heart to think of him going to bed 'unsatisfied.' I BF just before leaving for work at 7.15 ish, but DS2 doesn't go to bed until around 8.30 which is when DP offers the bottle. He then wakes up at least 3 times to feed in the night, including at around 5am a sort of cluster feed which can go on for 2 hours! Then DS1 is up and once again I have hardly slept!
So, what should I be doing/trying to get DS2 to drink a bottle or sleep a bit better? I feel guilty for leaving him, guilty for not EBFing him but also so so tired from work and the holidays and the lack of sleep-any help would be gratefully received! Thank you!
