My DS was 6 months yesterday, and he is going through exactly the same thing, waking every 2 hours. I am afraid it is a case of accidental parenting. I am just lucky i don't have to go back to work yet, so i sympathize with you moms that are going back.
I realise this isn't my post, and i am new to using this site, so i apologise if i have done this the wrong way, but i will write my situation too, in case anyone can offer me any advice, that i hope may help other moms and dads too.
In a nut shell, he has never slept though the night, max. 5 hours. He is a big boy, born big, ex.bf and we started a modified sort of baby-led weaning last week. All good there. We also returned 2 weeks ago from 2 weeks at my mother's, where his routine got all messed up and he ended up sleeping with me in my bed! Bliss!
But, he got use to feeding on tap all night! ;( So for the last week I've got him back on a 4 hr routine, extended naps, all good...BUT at night i am still trying to wean him off the breast. I have been sleeping next to his cot, in his room in spare bed, using Pu/pd. I thought we were making progress but last night I went to bed early, DH was to give the dream-feed (he usually wakes up for it at 10.30 otherwise it really is a "dream" feed at about 11)! It didn't go down well, FIRST he refused the bottle, and he freaked out when he realised Mommy was nowhere to be seen. So after 20 minutes of DH trying to calm him down and feed him, i gave the boob. Then he wouldn't go to sleep without holding my hand, i moved the cot next to the spare bed and positioned the pillows so i could drift off too. Now i have to say that 2 months ago, a friend/neighbour, who worked as a nanny years ago, came over to sleep the night and give me a break, at 4.30am (usual feed time) gave a feed of expressed milk....the next night she didn't feed him, just gave cuddles, and he settled back to sleep eventually, the next day she offered to stay another night and persuaded me to let him got the night without a feed and without being picked up, but let him settle himself back to sleep with her still being there in the room with him, while i tried to sleep in our room with earplugs in! Well, we did it, i suppose that was CIO?? Obviously he eventually settled himself after 30 mins of crying. I felt so bad the next day i said never again. I worry now that this is coming back to haunt me and he doesn't trust me anymore.
If anyone can see anything screamingly obvious, or just to say yes, you're right, keep doing what you're doing, please let me know....i would really appreciate it. BTW he is an ANGEL baby, but i haven't slept a whole night in over 6 months and i need to get this back on track....also DH is really starting to miss US!
