So my husband has gotten our daughter used to being rocked to sleep if not she won't sleep unless in the morning when he's gone and she wakes up to eat at 6 or 7 she'll go back to sleep after she eats no need to rock her but at night takes forever to put her to sleep and will only sleep if she's rocked. I told him it's going to be difficult for her to sleep on her own and even her pediatrician told him now I don't know what to do. He keeps picking her up when she starts crying and she seems to be hungry so much at night as well and she's teething. I'm a frustrated mom tonight. ‼️‼️
